Zusammenfassung: | The invention relates to a method for producing a component (5) for a vehicle, having the following steps: (A) providing a workpiece made of a heat-treatable steel material (2), said workpiece being provided with a zinc-containing coating on both sides, (B) at least partly heating the workpiece to a temperature above Ac1, (C) introducing the at least partly heated workpiece into a hot-forming and/or press-hardening tool which comprises at least one punch and at least one die, (D) closing the tool by moving the punch and/or the die relative to each other and hot-forming and/or press-hardening the workpiece, wherein at least one region of the heated workpiece is cooled in the closed tool such that a hardened microstructure is at least partly formed. The aim of the invention is to provide a method for producing a component for a vehicle, a component for a vehicle, and a use of the component, wherein together with an active corrosion protection, a sufficient component strength in the eventof a crash and a suffici |
