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.
Working in partnership VAMA, GONVAMA and car manufacturer Voyah announced the successful development of a new product for the lower car body – the hot stamped laser welded H-Frame, using the ArcelorMittal Multi Part Integration™ (MPI) breakthrough technology. The announcement was made at the 2021-2022 International Automotive Lightweight Conference in Yangzhou, China.
Chrysler’s all-new Pacifica is among the safest utility vehicles on North American roads thanks to its extensive use of advanced steels (72% of the body structure). The vehicle also features ArcelorMittal’s S-in motion® five-piece laser-welded door ring.
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.
Honda’s 2014 Acura model features a single-piece laser-welded door ring design, a world first. Developed by Honda in cooperation with ArcelorMittal and ArcelorMittal Tailored Blanks, the laser-welded design replaced a conventional multi-piece spot-welded version.
Watch the first video episode of Driving steel. With ArcelorMittal’s expertise in hot stamping steel and AP&T’s leadership in press-hardening equipment, this partnership is driving the development of advanced solutions, such as ArcelorMittal Multi Part Integration® (MPI). AP&T's advanced machinery has been successfully installed in various regions worldwide. Discover how such a large press-hardening installation works through the animation in this video.
ArcelorMittal and its partners continue to drive innovation in automotive manufacturing. The Steel E-Motive programme, an ambitious initiative by WorldAutoSteel, aims to revolutionise future mobility through autonomy and sustainability thanks to smart steel and ArcelorMittal Multi Part Integration® solutions.
In a rapidly evolving automotive industry, flexibility wins. ArcelorMittal Multi Part Integration® (MPI) maximises automotive manufacturers’ ability to adapt through the power of less: less parts, less process, less floor space, less time, less materials, less CO2 and less assembly cost.
Harness the strength of steel and the power of less.
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.
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.
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.
