Discover the power of less with MPI

ArcelorMittal is proud to spotlight its collaboration with Renault Group and its contribution to the innovative Renault Emblème project, a demo car designed to meet the challenges of low-carbon mobility. This collaboration is a testament to both companies' commitment to innovation and sustainability, demonstrating how the automotive and steel industries can unite to achieve ambitious decarbonisation goals.

ArcelorMittal announced that it is proceeding with plans to build an advanced, non-grain-oriented electrical steel (NOES) manufacturing facility in Alabama (USA). The new facility, wholly owned by ArcelorMittal, will be capable of producing up to 150,000 metric tons of NOES annually, depending on the product mix, in support of automotive and mobility, and other industrial and commercial uses of NOES, including electric motors, generators, and specialized applications.

Zagnelis^® coatings have been specially designed to add a stage in vehicle corrosion protection, while meeting vehicle manufacturers' specifications: drawing, welding properties etc. In particular, they offer corrosion resistance far superior to that provided by traditional zinc-based coatings. The presence of magnesium in the coating promotes the formation of compact corrosion products highly stable over time, thereby substantially reducing coating consumption dynamics and enhancing edge protection.

Zagnelis^® coatings also offer excellent drawability performance due to outstanding tribological properties for a zinc-based coating.

ArcelorMittal has been working with automakers for years to co-engineer steel solutions that address safety, strength and fuel economy concerns in the most cost-effective way. ArcelorMittal offers an array of lightweight steel solutions and has seen tremendous growth and evolution of its door ring solution, co-engineered with Honda R&D Americas.

ArcelorMittal is transforming the auto industry from the inside out. ArcelorMittal, the world’s leading steel and mining company, is continually developing lightweight steel solutions that make vehicles lighter, safer and more sustainable.

Steel recycling and sustainability go hand-in-hand

The automotive landscape is rapidly evolving, driven by the electrification of vehicles and the emergence of new market players. As carmakers navigate the complexities of balancing internal combustion engine (ICE) and battery electric vehicle (BEV) production, ArcelorMittal’s Multi Part Integration^® (MPI) offers a transformative approach. This white paper discusses how MPI technology helps streamline automotive manufacturing, reduce the number of parts, and achieve significant CO2 savings—all while meeting stringent performance standards for safety and lightweighting.

A patch is a piece of steel which is welded directly to a ‘mother’ blank before stamping. The steel grade and/or the thickness of the patch can differ from that of the mother blank. 

Using a patch enables OEMs to tailor a specific area of a final component. For example, a patched blank can cost-effectively improve a vehicle’s crash performance. 

Patched blanks are ideal for managing energy absorption and are already helping automakers to meet crash test requirements.

To prove the validity of the MPI concept, teams from ArcelorMittal Tailored Blanks and ArcelorMittal Global R&D have developed a new LWB H-Frame solution for the rear of an SUV vehicle. The S-in motion^® SUV was used as the basis for the design.

PSA award recognises the value ArcelorMittal adds to the partnership. Both companies work together to create the vehicles of the future with the next generation of steel solutions.
