Luxembourg-based steelmaker ArcelorMittal has announced a partnership with French automaker Renault Group focused on sustainable mobility, marked by the start of deliveries of low-emission steel for electric vehicle (EV) production.
Since September 2025, ArcelorMittal has been supplying its Usibor® 1500 XCarb® steel for five hot-stamped structural components used in several Renault models.
Low-carbon steel production with EAF route
The steel is produced via an electric arc furnace route using 75 percent recycled content and powered entirely by renewable electricity. This production method enables a reduction in carbon emissions of nearly 70 percent compared to conventional blast furnace-based steelmaking, supporting the decarbonization of the automotive supply chain.
For several years, the Renault Group has used Usibor® 1500 for its body structural components. Now, as part of its broader decarbonization strategy, Renault has collaborated with ArcelorMittal to validate multiple steel grades developed under the XCarb® initiative.
The newly approved XCarb® version of Usibor® 1500 maintains the same mechanical performance and safety characteristics as conventional grades while significantly reducing the carbon footprint of vehicle components.
The use of advanced low-carbon steel supports both emissions reduction targets and lightweight vehicle design, contributing to improved efficiency in electric vehicles.
