Abstract
A method for the production of press-hardened components, in particular a vehicle body component, from a semifinished product () made of unhardened, hot-workable steel sheet. A component blank () is formed from the semifinished product (), pre-coated with a first coating (), by a cold-forming method, in particular a drawing method. The component blank () is trimmed at the margins to a marginal contour (') approximately corresponding to the component () to be produced. The trimmed component blank () is heated and press-hardened in a hot-forming tool (); then the press-hardened component blank () is covered with a second, anticorrosion coating () in a coating step.
