ArcelorMittal has recently launched two new record wide flange shapes of up to 1488kg/m (1000lbs/ft)! W14x930 and W14x1000 are approved per ASTM A6 and available in A992 and A913 grades.

XCarb® recycled and renewably produced W14x930 and W14x1000

These impressive hot rolled sections, rolled at ArcelorMittal's Differdange mill in Luxembourg, are part of the XCarb® recycled and renewably produced steel offer as they are produced from 100% scrap in an electric arc furnace powered by renewable energy.

The expanded range of jumbo shapes offers an efficient alternative to built-up or plated sections for applications where loads or stiffness demands are too large for conventional rolled sections.

Circularity is certainly not a new concept in the world of steel, and it covers much more than simply recycling scrap steel…

The 3 Rs

Reduce. One way we may protect primary materials and improve circularity is by using less steel. Advanced high strength steels, such as ArcelorMittal’s Amstrong®, Amstrong® Ultra, and HISTAR®, are all being utilised to optimise weight in construction, reducing the amount of steel required.

Reuse. Upon reaching the end of its life, steel can be fully recycled and reused so it makes sense to reuse it when possible. This reduces carbon emissions as no new steel needs to be produced.

Recycle. When it comes to recycling, the fact that steel is magnetic is a major benefit. Steel is more easily extracted from waste streams than any other material. In doing this, it is guaranteed that almost all steel is collected and recycled into new steel products.

Circularity of by-products

Natural resource preservation can benefit from the by-products of industries, such as the steel industry. With the help of ArcelorMittal's Smart Carbon technology, carbon from waste streams, such as responsibly sourced construction wood waste, can partially replace the coal used in blast furnaces.

The Smart Carbon technology also allows for the integration of carbon capture and reutilisation (CCU) or storage (CCS) technologies. It is possible to recover and reuse carbon emissions from the steelmaking process, thereby potentially producing a product with zero carbon emissions. According to the UN Intergovernmental Panel on Climate Change and the International Energy Agency, these technologies are essential to reaching net-zero steel production by 2050.

ArcelorMittal Gent in Belgium has recently commissioned the Torero plant. The project will reduce the amount of fossil coal required by transforming waste wood into bio-coal for use in the blast furnace. Using bio-coal results in a bio-gas which can be transformed into ethanol at the plant’s Steelanol (Carbalyst) facility. The bio-ethanol can then be used in the production of a variety of chemical products, such as transport fuels, which will help the chemical sector circumvent the use of fossil fuels.

ArcelorMittal’s Innovative DRI (direct reduced iron) pathway is another technology being developed. DRI, along with recycled steel, is a key metallic input in an Electric Arc Furnace (EAF). DRI is commonly produced using natural gas; however, Innovative DRI instead uses an alternate, clean energy source such as hydrogen. It is possible to create zero-carbon DRI if the hydrogen is produced using renewable electricity.

Steel will continue to play a significant role in the circular economy of the future – benefitting society, the environment, the economy, and our future – with the help of these initiatives.

ArcelorMittal has begun mass production of Magnelis® steel at its galvanising line no. 1 in Avilés, Spain, making the Spanish site one of the main Magnelis® production plants within the ArcelorMittal Group. ArcelorMittal’s Magnelis® is a metallic coated steel that offers exceptional corrosion resistance and ensures optimal surface protection against long-term wear and tear.

Large scale production of Magnelis®

Production on a large scale started in March on galvanising line no. 1, after several months of work to adapt the line, including a large number of tests to validate the product.

The close collaboration between the various technical teams at ArcelorMittal and the plant’s experience with this product – production of Magnelis® began on line no. 2 in 2017 – have been crucial in achieving this ambitious goal.

The cumulated production of more than 500 000 tonnes of Magnelis® on line no. 2, together with the production of heavy plate for wind towers, place ArcelorMittal Asturias as a benchmark for the production of steel used in renewable energy projects.

XCarb® recycled and renewably produced Magnelis®

This is not the only progress achieved in recent months regarding the production of Magnelis® in Avilés. It is possible to produce Magnelis® with a reduced CO2 footprint thanks to XCarb® recycled and renewably produced, which leads to a 65% reduction in CO2 emissions from the production process compared with Magnelis® produced via the conventional steelmaking route. Moreover, thanks to the support of the Global R&D teams, it is possible to produce high strength steels coated with Magnelis®, thereby reducing the weight of structures by up to 20% and improving installation speed and quality.

In recent years, Magnelis® has established its position as the product of choice for applications in the solar sector and others such as racking systems, silos, and HVAC as it offers clear advantages over competing materials thanks to its outstanding corrosion resistance and the product guarantees issued by ArcelorMittal for every project. It provides a comprehensive solution that meets the requirements for both aerial structures and those buried in the soil. For the latter use, ArcelorMittal has developed a range of thicker coatings (ZM620 and ZM800) that can be covered by guarantees of up to 25 years for applications in different types of soils.

XCarb® steel bars and wires for the construction industry and energy sector

The demand for XCarb® recycled and renewably produced steel is increasing in the construction industry and energy sectors: More than 80% of the components in a wind turbine and its related infrastructure are made with steel. ArcelorMittal’s steels have been successfully used in the manufacturing of more than 10 000 onshore and offshore wind turbine towers since 2005. ArcelorMittal produces an extensive portfolio of steels which are used in the major components of a wind farm: foundations, towers, nacelles, generators, gearboxes, yaws, pitches, mooring ropes, and power cables.

Bars and rods play a major role too. Rebars (concrete reinforcement bars) are used for onshore and offshore foundations. The business division WireSolutions produces several solutions for the wind industry, such as mooring ropes, sheathed spiral strand wire, sockets, and offshore transportation reels, as well as high performance hoisting ropes for the most demanding environments and XCarb® recycled and renewably produced galvanised low carbon steel wire for cable armouring.

Steel is also used as a reinforcement element in concrete or cables for the construction industry. These product families are mainly wire rod mesh, rebars in bars or rebars in coils, and high Carbon Prestressed Steels (PSC). Regulations are more demanding in the Nordics, but all countries follow the same trends. The more demanding customers are the governmental ones. For new buildings and infrastructures, requirements now include thresholds regarding the carbon footprint. New projects are approved when the CO2 footprint meets the requirements.

WireSolutions will also present an extensive line up of products featuring low carbon emissions steel catering to various needs such as window fasteners, wire ropes, wiper arms, cable armouring wire, cold heading quality materials, steel fibres, bright bars, fencing, and nails.

One of the most recent notable innovations is the introduction of a new generation of Free Cutting Steel, called 3eCut®, which boasts equivalent mechanical properties to the standard leaded grade 11SMnPb30.
