<p>The invention relates to a method for producing hardened parts from sheet steel, comprising the following method steps: a) shaping formed parts made from a sheet steel provided with a cathodic corrosion protection, whereby; b) before, during or after shaping the formed part, a necessary end trimming of the formed part and, if necessary, required stampings or the production of a hole pattern is carried out, whereby; c) the formed part is subsequently heated, at least in partial areas and with the admission of atmospheric oxygen, to a temperature that enables an austenitizing of the steel material, and; d) the part is then transferred into a shape hardening tool, a shape hardening is carried out inside the shape hardening tool, during which the part is cooled and hardened by setting and pressing the part through the shape hardening tools.</p> |
