Steel is the main component of cold-formed body parts such as those produced by Kirchhoff Automotive, located in southern Westphalia. Through the collaboration, Kirchhoff’s safety-relevant structural components will be manufactured with SSAB’s proprietary SSAB Fossil-free Steel. The automotive supplier announced earlier this year a similar cooperation with ArcelorMittal (see Kallanish 2 March 2023).
Kirchhoff’s crash boxes, lower beams and closure plates are manufactured using the cold forming process, and the individual parts weigh between 300g and 1.3kg. By using SSAB Fossil-free Steel, Kirchhoff expects to cut almost 40% of emissions in the production of a front bumper.
SSAB Fossil-free Steel uses direct reduced iron and is produced without using fossil energy. Instead, biogas and fossil-free electricity are used. The quality and properties of this material are just as good as those of the steel conventionally produced by SSAB, the steelmaker points out.
