MX3D 3D Prints Stainless Steel Floor for Lunar Habitats Village
By Strategic Research Institute on Sep 09, 2021 08:53 am

Multiple space agencies and commercial space entities will be taking us back to the Moon, with goal of establishing the necessary infrastructure to keep going back. In particular, NASA, the ESA, Roscosmos, and China are all planning on establishing outposts that will allow for scientific research and a sustained human presence. The ESA is currently showcasing what its outpost will look like at the 17th annual Architecture Exhibition at the La Biennale di Venezia museum in Venice. It’s known as the International Moon Village, which was designed by the architecture firm Skidmore, Owings & Merrill with technical support from the ESA. This same company recently unveiled a prototype of the skeletal metal component that will one day be part of the Village’s lunar habitats. The component was built by MX3D, an Amersterdam-based 3D printing architecture and design firm specializing in Wire Arc Additive Manufacturing. This process involves fusing metal wires with lasers to create lightweight metal objects with high structural strength.

Designed to meet efficiency, use, and construction constraints, the structure’s smooth web pattern design emerged from delineating stress map analysis and optimising a continuous topology to reduce mass and make maximum use of 3D printing manufacturing methods. The skeletal, smooth web pattern will be part of the flooring for each habitat that collectively makes up the ESA’s International Lunar Village. The prototype was created using a robotic 3D printer out of 308LSi stainless steel over the course of about 10 days, measures 4.5 meters in diameter, and has a total mass of approximately 395 kgs.

The floor component consists of six separate segments that were printed vertically before being welded together. When integrated with SOM’s design for a four-story semi-inflatable habitat, the 3D printed structure will be supported by three columns and covered by a series of floor panels. The flooring and manufacturing process are consistent with SOM’s habitat design, which calls for four-story semi-inflatable shells that collectively make the International Lunar Village. Each semi-inflatable shell structure measures four stories high and offers the highest possible volume to mass ratio. Once inflated on the lunar surface, each of these habitats will approximately double its original internal volume.

The module’s inflatable design allows it to be compressed for the sake of transport and then inflated to its full size once it is deployed to the lunar surface. But unlike previous inflatable designs, where the structural and mechanical systems are typically at the center, SOM’s design allows for an open interior that optimizes the living experience.

Indian Stainless Steel Makers Seek Reinstatement of CVD on Imports

Strategic Research Institute
Published on :
29 Sep, 2021, 5:55 am

Indian stainless steel producers have sought government intervention and imposition of countervailing duty on imported stainless steel pointing out 177% increase in inward shipment during April-July 2021, YoY basis. All India Stainless Steel Cold Rollers’ Association said that “In national budget 2021-22 presented earlier in the year, countervailing duty on stainless steel imports from China was suspended until September 30, 2021 and levy on shipments from Indonesia was revoked which triggered floodgates of imports to detriment of domestic producers.”

It said that “The industry is still recovering from impact of Covid-19 and if countervailing levy is not imposed immediately, small and medium scale producers will be forced to shut down their plants and become traders.”

Import of stainless steel in the first four months of 2021-22 was about 177% higher than the year-ago period. As per All India Stainless Steel Cold Rollers’ Association, from a monthly average of 34,105 tonnes in 2020-2021, the April-July average is 60,214 tonnes and in July 2021 alone, it was 77,337 tonnes.

The Indian stainless steel sector has an annual total capacity of more than 5 million tonnes. MSME sector contributes nearly one-third or 1.4 million tonnes to the stainless steel capacity. The rest of the capacity is of Jindal Stainless with 1.9 million tonnes, 340,000 tonnes from Salem Steel, while 1.45 million tonnes comes from a couple of private players such as BRG, Rimjhim, Shah Alloys and Valley Iron etc.

WTO Forms Dispute Panel for Chinese AD Duties on Stainless Steel

Strategic Research Institute
Published on :
29 Sep, 2021, 5:59 am

World Trade Organization’s Dispute Settlement Body has established a panel on 27 September, as requested by Japan, regarding China’s measure imposing anti-dumping duties on stainless steel products from Japan. In July 2019, China started imposing anti-dumping duties on stainless steel products imported from Japan, the Republic of Korea, Indonesia, and the EU, claiming that its domestic industry is being injured by the dumped imports of such products.

Japan considers the AD measure to be inconsistent with the General Agreement on Tariffs and Trade 1994 due to flaws in the Chinese authorities’ determination and its investigation procedures. Japan has repeatedly asked China to abolish the AD measure at the WTO and in bilateral meetings. Japan requested consultations with China under the WTO Agreement on June 11, 2021. Japan and China held such consultations on July 19, 2021. However, as the dispute was not settled through the consultations, Japan subsequently requested the establishment of a panel under the WTO Agreement.

Japan will pursue an appropriate solution on this issue in accordance with the rules under the WTO Agreement.

The total value of exports of stainless steel from Japan to China is approximately 70 billion yen per year, of which exports of the products subject to the AD measure account for approximately 9.2 billion yen (both figures as of 2019).

Leading Philippine’s nickel miner Global Ferronickel Holdings Inc said its USD 50 million rebar steel rolling plant project in Bataan will be impemented next year and that it intends to bear the entire cost of the project. Global Ferronickel Holdings President Mr Dante R Bravo said “The project is still going to push through except that we are going to own it 100%. We decided to put all the investments by ourselves instead of partnering with other parties. We believe that we have the capacity to do that. Only at this point we are hampered by the Covid-19 pandemic. But we will push with that. We cannot do construction this year, next year possibly.”

Two years ago, Global Ferronickel Holdings announced that it has partnered with Hong Kong-based Huarong Asia Ltd. for the steel plant, with Huarong shouldering 51% of the total investment. The start of the commercial operations for steel plant project, which was unveiled by Global Ferronickel Holdings in mid-2019, was targeted to start by 2022. However, the Covid-19 pandemic derailed the project’s timeline.

The rebar steel-rolling plant will have an annual production capacity of 600,000 tonnes. With the steel plant project, the company is aiming to corner 5% of the 10-million tonne local steel market.

Global Ferronickel Holdings FNI is the second-largest nickel producer in Phiippines. The company through unit Platinum Group Metals Corp operates a mine in Surigao del Norte.

Jindal Stainless Reports Strong Performance in July-September Quarter

Indian stainless steel giant Jindal Stainless Limited announced that an overall healthy demand environment post the second wave of COVID in Q1 of FY22 pulled up sales volume by 8% over Q1FY22, to 256,664 tonnes in Q2of FY22. The upward rally in prices of input materials continued unabated throughout the second quarter. The average LME prices of Nickel and Ferro-chrome in Q2FY22 climbed by 10% and 21% respectively over Q1FY22, which had a positive impact on inventory valuation. This, along with an improved volume mix, led to a 23% increase in EBITDA in Q2 of FY22 over the sequential quarter. On a standalone basis, JSL’s EBITDA and profit after tax stood at INR 711 crore and INR 363 crore respectively.

All major end-use segments like process industry, Pipe & Tube, Railways & Wagons, and Metro Rail grew during the quarter keeping the stainless steel demand firm. As general manufacturing picked-up pace during the quarter, demand for special grades like duplex and super austenitic, where JSL is an established supplier, also gained momentum. Auto segment sales remained weak on account of the long waiting period necessitated by semiconductor shortage. Despite prevailing logistical challenges due to container scarcity, JSL maintained strong operational performance through advance planning and strategic sourcing of raw materials.

Company increased its exports percentage from 20% in Q1 of FY22 to 23% during Q2 of FY22 to counter the continual surge in imports of stainless steel from China and Chinese-funded investments in Indonesia.

Acerinox on Track to Achieve Best Results Ever in 2021

Spanish stainless steel giant Acerinox reported that profit after tax and non-controlling interests in the first nine months of 2021 amounted to EUR 373 million as compared to EUR 31 million in January to September 2020. Meltshop production increased by 26% YoY to 1,992,038 tonnes and revenue totalled EUR 4,769 million, a 38% increase compared to the first nine months of 2020. EBITDA, at EUR 671 million, was 2.7 times higher and the EBITDA margin rose to 14%. These results are driven by the strong performance of the US market. All of the Acerinox Group’s business units are recognising positive results, although the improvement seen in Acerinox Europa is being limited by the rise in energy costs. Acerinox CEO Mr Bernardo Velázquez said “Cost control management and efficiency improvements have enabled us to take advantage of the good market situation.”

The strong activity was maintained across all markets in the third quarter. In the third quarter of the year, the strong activity in the stainless steel division was maintained across all markets, and pre-Covid levels were achieved in the high-performance alloys division. In the aforementioned quarter, profit after tax and non-controlling interests amounted to EUR 171 million, 6 times higher than in the third quarter of 2020 (37% higher than in the second quarter of 2021). EBITDA, which totalled EUR 293 million, was 3.3 times higher than in the third quarter of 2020 (representing a 35% increase on the second quarter of 2021). The EBITDA margin was 17%. Between July and September, revenue, amounting to EUR 1,703 million, increased by 52% in comparison with the third quarter of 2020 (representing a 5% increase on the second quarter of 2021).

Acerinox said “The positive backlog situation, in both the stainless steel and high performance alloys divisions, affords the Group to have visibility until the first quarter of 2022. Despite the end-of-year seasonality, Acerinox estimates that EBITDA will improve slightly from the third to the fourth quarter, due to strong demand and low inventory levels. If these forecasts prove correct, the Group will achieve its best results ever.”

Klöckner Metal Publishes Guide to Grades Of Stainless Steel

Strategic Research Institute
Published on :
11 Nov, 2021, 4:54 am

Klöckner & Co SE’s North American subsidiary Kloeckner Metals Corporation has published a Guide to Grades of Stainless Steel. The term stainless steel refers to any of several iron-based alloys that include the element chromium as at least 10.5% of their composition. Although all stainless steel is defined by its crystalline structure, the metal comes in more than 100 grades. The American Iron and Steel Institute first developed a structure of grades for steel in the 1930s and 40s. Later, this system combined with one from the Society of Automotive Engineers International to form a more standardized numbering system. Today, steel manufacturers may use more than one numbering system, however, which can complicate matters.

The general idea behind grading the metal is that stainless steel can be divided into three broad categories austenitic, ferritic, and martensitic, based on the crystalline structure of its iron atoms. Each category is further divided into series and grades. The grades reflect the specific alloy’s durability, quality, and temperature resistance. Numbers listed after the grade refer to the item’s chemical composition, specifically to it’s chromium and nickel percentages. The 300 series of stainless steel is the most common with 304 stainless steels and 316 stainless steels being the most prevalent grades. Two other common grades are 409 stainless steels and 430 stainless steels.

300 Stainless Series Stainless Steel Grades

Stainless steel grades in the 300 series are classified as austenitic with 18-30% chromium and 6-20% nickel as their major alloying additions. It is solid iron containing face-centered cubic crystals. The composition of 300-series stainless steel grades makes it especially useful in the construction, automotive, and aerospace industries. Since it can withstand extremely high temperatures, series 300 stainless steel is hardenable only by cold working methods.

301 Stainless Series Stainless Steel Grades

Attractive and malleable, grade 301 features high strength and corrosion-resistant composition. It is highly malleable and abrasion resistant, grade 301 stainless steels often gets used for decorative structural applications.

304 Stainless Series Stainless Steel Grades

Grade 304 represents 50% of the steel produced around the world. Grade 304 contains 18% chromium and 8% nickel, which makes it aesthetically pleasing as well as durable. Its one weakness is saline, so grade 304 can pit or crevice when used near salt water.

316 Stainless Series Stainless Steel Grades

The second most commonly produced steel, grade 316 contains 2-3% molybdenum. Consequently, it’s more resistant to saline and thus better for coastal environments. Many surgical supplies also get made from grade 316 stainless steels. Kloeckner Metals supplies the ultra low carbon variant of this grade stainless steel.

317 Stainless Series Stainless Steel Grades

This grade provides high tensile strength at elevated temperatures. It is more resistant to corrosion and pitting than either grade 304 or grade 316 stainless steels. Due to its composition, grade 317 stainless steel is a more expensive alloy than most other 300-level grades.

400 Stainless Series Stainless Steel Grades

This series of stainless steel contains 11% chromium and 1% more manganese than 300-series grades, making it slightly magnetic. This steel also features higher carbon content. As a result, 400-series stainless steel offers higher strength and more wear resistance, but it is also more easily corroded than 300-series grades. Heat-treating hardens 400-series stainless steel.

430 Stainless Series Stainless Steel Grades

Ferritic steel, grade 430 forms easily but does not resist extreme temperatures or corrosion well. It’s often used for decorative purposes such as automotive trim. Grade 430 stainless steels is also commonly used in backyard barbecue grills. It is less expensive than grade 304 since it does not contain nickel. 430 stainless steel sheets are routinely stocked.

434 Stainless Series Stainless Steel Grades

Among the most widely used ferritic steels, grade 434 is highly corrosion and oxidation resistant. It can also resist temperatures of up to 1500°F. Grade 434 stainless steel cannot be hardened by heat treatment and is generally cold formed like low carbon steel. It is typically used for automotive trim.

420 Stainless Series Stainless Steel Grades

Grade 420 stainless steel is a very bright steel and one of the earliest carbon/iron alloys. Containing 12% chromium, this grade of steel is highly corrosion resistant. It is often called “blade grade steel” since manufacturers frequently use it to make surgical instruments.

904L Stainless Series Stainless Steel Grades

A non-stabilized austenitic stainless steel, 904L grade products contain copper as part of the alloy. As a result, this grade of steel can resist corrosion from many acids. The high cost of this grade of stainless steel, however, has caused many manufacturers to turn to the lower-cost duplex stainless steel 2205 as an alternative.

The SAE developed a four-digit grading system for carbon steel and a three-digit one for stainless steel. The first digit refers to the primary alloy element, the second and third digits to the alloy’s carbon percentage. Carbon steel needs four digits because there are more carbon steel alloys than stainless steel alloys. The ASTM developed a six-digit system for categorizing stainless steel. Composed of both letters and numbers, this classification system begins with the letter A, which stands for any ferrous material, followed by a sequential series of numbers unrelated to the metal’s properties. The letter M, standing for “metric,” follows this number series. The last two digits refer to the year the standard for the grade was adopted or last revised. Other organizations have also published grades and series of steel, including the British Standards BS, German Standard DIN, Chinese Standard GB, European Standard EN, Japanese Industrial Standards JIS and the International Organization for Standardization IOS. Each system functions entirely differently.

EU Imposes AD Duty on Stainless Steel from India & Indonesia

Strategic Research Institute
Published on :
19 Nov, 2021, 5:16 am

The European Union has imposed tariffs on imports of cold-rolled flat stainless steel products from India and Indonesia after an investigation found they were being sold at artificially low prices. The European Commission has set duties of 10.2% for Indonesia's IRNC and 20.2% for other Indonesian producers. The rates for India are 13.9% for Jindal Stainless Ltd and Jindal Stainless Hisar Ltd and 35.3% for other Indian producers. The anti-dumping duties will take effect from 19 November 2021

The European Commission has confirmed imports of stainless steel from India and Indonesia were sold at dumped prices. Producers in both countries now subject to measures have been benefiting from major distortions in the cost of raw materials. It is essential that the European Commission addresses to the fullest extent both dumped and subsidised exports of SSCR from India and Indonesia.

The investigation leading up to these provisional measures was initiated on 30 September 2020 following a complaint submitted by EUROFER. The Commission said that the anti-dumping duties aim to remedy damage caused to EU producers such as Acerinox and Outokumpu

The Commission has imposed provisional anti-dumping duty rates ranging from 13.6% to 34.6% from India, and from 19.9% to 20.2% on imports from Indonesia in May 2021.

The Commission investigation confirmed that dumped imports from India and Indonesia increased by more than 50% in the period considered and their market share almost doubled. Imports from the two countries undercut EU producers’ sale prices up to 13.4%, while the underselling was higher, exceeding 23% up to 34.6%.

Chinese Researchers Develop Anti COVID19 Stainless Steel

Strategic Research Institute
Published on :
02 Dec, 2021, 4:58 am

Severe acute respiratory syndrome coronavirus 2 exhibits strong stability on conventional stainless steel surface, with infectious virus detected even after two days, posing a high risk of virus transmission via surface touching in public areas. In order to mitigate the surface toughing transmission, Chinese researchers have developd the first SS with excellent anti-pathogen properties against SARS-COV-2. The stabilities of SARS-CoV-2, H1N1 influenza A virus and Escherichia coli on the surfaces of Cu-contained SS, pure Cu, Ag-contained SS, and pure Ag were investigated. It is discovered that pure Ag and Ag-contained SS surfaces do not display apparent inhibitory effects on SARS-CoV-2 and H1N1. In comparison, both pure Cu and Cu-contained SS with a high Cu content exhibit significant antiviral properties. Significantly, the developed anti-pathogen SS with 20 wt.% Cu can distinctly reduce 99.75% and 99.99% of viable SARS-CoV-2 on its surface within 3 and 6 hours, respectively. In addition, the present anti-pathogen SS also exhibits an excellent inactivation ability for H1N1 influenza A virus and Escherichia coli. Interestingly, the Cu ion concentration released from the anti-pathogen SS with 10 wt% and 20 wt% Cu was notably higher than the Ag ion concentration released from Ag and the Ag-contained SS. Lift buttons made of the present anti-pathogen SS are produced using mature powder metallurgy technique, demonstrating its potential applications in public areas and fighting the transmission of SARS-CoV-2 and other pathogens via surface touching.

The transmission of pathogenic bacteria and viruses in public areas has been a long-standing issue for public health. Infectious diseases induced by these bacteria or viruses are not only afflicting millions of people annually but also causing an immeasurable economic cost. In particular, the current coronavirus disease 2019 is causing a global pandemic.

As the two most popular inorganic antimicrobial elements, Ag and Cu have attracted significant research interests because of their low toxicity to animal cells and well-known ability to inactivate a broad spectrum of bacteria and viruses. Studies have reported that Ag nanoparticles, some Ag-contained composites, copper, brass, and Cu-contained high-entropy alloy have antimicrobial properties. In particular, it has been reported that pure Cu exhibits an excellent antiviral efficiency towards SARS-CoV-2 and H1N1 influenza A virus. However, replacing SS products with pure Cu in public areas is impractical due to its high cost, low strength, and less corrosion-resistant capability. Some studies have introduced antimicrobial properties into conventional SS by surface coating or ion implantation. Nevertheless, it is necessary to note that the thickness of coatings is limited (e.g., physical vapor deposition, cold-spray, and ion implantation, thickness < 1 mm). The damage of coatings on the surface can significantly affect the antimicrobial properties of SS, resulting in a limited service duration. Therefore, low-cost SS with long-term antimicrobial properties is required for replacing conventional SS products used in public areas.

Scientists Increase the Endurance of Stainless Steel by 1.8 Times

Strategic Research Institute
Published on :
06 Dec, 2021, 4:57 am

Scientists from Russia, Italy and Turkey found the optimal parameters for cold working on steel to increase the endurance of 316L steel by 81.25%. To improve the properties of metal parts, the metal surface is usually treated with temperature methods - the material is heated and cooled. Stainless steel AISI 316L is a common alloy that is used for the production of chemical and aerospace equipment, biomaterials, handrails in the pool, jewelry. A possible alternative to temperature treatment is shot peening. A strong air flow strike the metal with small particles. This makes the surface harder and creates residual compression stresses, as well as reduces the grain size. Scientist from RUDN University together with colleagues from Italy and Turkey found out that shot peening increases the endurance of AISI 316L steel.

Scientists experimentally investigated 42 types of shot peening with different intensity and different coverage area. They have determined the microstructure of steel after processing, grain size, surface topography, hardness, wettability and other parameters. The researchers also found optimal peening parameters and studied the residual stress, the ability not to collapse under the action of cyclic loads, of stainless steel treated in this way.

The optimal parameters turned out to be an intensity of about 25 (it is measured using the so-called Almen test by bending the test plate, which is subjected to the same treatment as the material under study) and 1500% coverage area (that is, the device passes through each area of the material 15 times). It turned out that this makes it possible to increase the fatigue strength of the material by 81.25%.

The results are published in Metals and Materials International.

ISSDA President Mr KK Pahuja said "The current market buoyancy is hiding the larger issue of import dependency, which goes against the Aatmanirbhar vision of Prime Minister and has long term implications. If prescribed trade remedies, imposed after laid down quasi-judicial procedures, are suddenly withdrawn, it creates huge policy uncertainty and adversely affects business sentiment. We hope government will take note of import surge and restore both the CVDs in the forthcoming Budget.”

ISSDA said “The decision to suspend the CVD in Union Budget 2021-22 has led to a surge in imports from Indonesia and China. The imports are being largely driven by Chinese companies operating from Indonesia, which got a boost after the suspension of CVD in February 2021.”

German KfW IPEX-Bank is providing USD 82 million in financing to support Austrian companies Primetals Technologies Austria GmbH and Andritz AG in supplying products and services to Jindal Stainless Limited. JSL is procuring capital equipment from Europe as part of its plan for an expansion of its production facilities in Jajpur in the Indian state of Odisha. The expanded facility is expected to increase stainless steel production capacity from 1.1 million tonnes per annum to 2.1 million tonnes per annum. Part of this capacity expansion is a new facility for producing and casting stainless steel. Additionally, a new combo line, direct rolling, annealing and pickling line, will be installed to increase the cold rolling mill capacity.

Promoting sustainable environmental and social aspects is an integral part of the financing. The financing is insured against economic and political risks by OeKB, the Austrian export credit agency. KfW IPEX-Bank’s financing supports European exports, which in turn secure jobs in Austria, Germany and Europe.

Jindal Stainless Limited is the largest manufacturer of stainless steel in India. The unit of Jindal Stainless Limited is located in the eastern part of India, in the state of Odisha. The manufacturing complex, equipped with ferro-alloy facility, world-class technology, and captive power generation facility, is eventually scalable up to 3.2 million tonnes per annum of stainless steel production.

Hong Kong Researchers Develop Anti COVID 19 Stainless Steel

Strategic Research Institute
Published on :
23 Dec, 2021, 4:42 am

Stainless steel is one of the most extensively used materials in many public areas and hygiene facilities but has no inherent antimicrobial properties. Additionally, the SARS-CoV-2 exhibits strong stability on regular SS surfaces, with viable viruses detected even after three days. Undoubtedly, this has created a high possibility of virus transmission among people using these areas and facilities. Now a project team led by Professor Mingxin HUANG at the Department of Mechanical Engineering of the Faculty of Engineering of the University of Hong Kong, in collaboration with Professor Leo Lit Man POON's research team at the Centre for Immunity and Infection of the LKS Faculty of Medicine of University of Hong Kong, has made significant breakthroughs in producing the first anti-COVID-19 stainless steel that kills the severe acute respiratory syndrome coronavirus 2 on its surface. The anti-COVID-19 stainless steel can also inactivate the H1N1 virus and E.coli on its surface. For initial demonstration purposes, floor buttons used in lifts were fabricated successfully using the high Cu SS (20 wt%)

Professor Mingxin Huang said "In this latest breakthrough, the inactivation of pathogen microbes, especially the SARS-CoV-2, on SS surface is achieved by tuning the chemical composition and microstructure of regular SS. The breakthrough also found interesting points about Ag and Cu as the allying elements to prepare anti-pathogen SS. Pathogen viruses like H1N1 and SARS-CoV-2 exhibit good stability on the surface of pure Ag and Cu-contained SS of low Cu content (e.g., = 5wt%) but are rapidly inactivated on the surface of pure Cu and Cu-contained SS of high Cu content (e.g., = 10 wt%)."

Professor Huang added "The present anti-COVID-19 SS can be mass produced using existing mature technologies. They can replace some of the frequently touched SS products in public areas to reduce the risk of accidental infection and fight the COVID-19 pandemic.”

A patent has been filed for the research findings. The team has been liaising with industrial partners to generate prototypes of public SS products such as lift buttons, doorknobs, and handrails for further tests and trials.

The findings were published in Chemical Engineering Journal on 25 November 2021 in the paper titled "Anti-pathogen stainless steel combating COVID-19".
