Abstract
Methods for producing steel components with well-adhering metallic coatings that provide protection from corrosion offer flexibility in processing qualities. In one example, a flat steel product comprising a steel material that is hardenable by quenching in a hot forming operation and that has a yield point of 150-1100 MPa and a tensile strength of 300-1200 MPa may be coated electrolytically with a thin zinc layer. From the flat steel product, a blank may then be obtained that is heated directly to at least 800° C. and then formed into the steel component. Alternatively, the blank may initially be formed into the steel component and then heated to at least 800° C. Either way, the steel component may then be hardened by sufficiently rapid cooling from a sufficiently high temperature.
