Tailored Blanks services

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.

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.

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.

ArcelorMittal is proud to spotlight its collaboration with Renault, and its contribution to the innovative Renault Emblème project, a demo car designed to meet the challenges of low-carbon mobility. This collaboration demonstrates how the automotive and steel industries can unite to achieve ambitious decarbonisation goals, showcasing a reduction of CO₂ emissions compared to conventional steelmaking by as much as 69%. 

Steel recycling and sustainability go hand-in-hand

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.

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.

Life cycle assessment (LCA) is an essential tool to evaluate the environmental performance of a material. By using LCA, the environmental impact of different materials can be compared.

In the first of a two-part series, Carl de Maré, head of technology strategy at ArcelorMittal explains steel’s role in creating a low-carbon, circular economy that works for everyone.

For the past four years, ArcelorMittal's XCarb^® initiative has been shaping the future of sustainable steel in the automotive industry. Through pioneering advancements and strategic collaborations, XCarb^® recycled and renewably produced steel has played a critical role in reducing the carbon footprint of vehicles while maintaining the highest standards of safety and performance.

David Clarke, ArcelorMittal’s head of strategy and chief technology officer, highlights the impact materials have on our planet, and how are we to mitigate the risks, while responding to the global demand for steel.
