Abstract

An automotive component is produced by hot forming and press hardening a hardenable steel alloy having a tensile strength of at least 1700 MPa. The hardenable steel alloy, in addition to a balance made up of iron and melting-related impurities, has the following alloy elements carbon, niobium, and titanium. The automotive component is coated by a thermal coating process.
