Abstract
A method for producing a structural and/or safety-related motor vehicle component having at least one hot-formed and press-hardened part constructed from high-strength steel includes the steps of partially heat-treating a region of the motor vehicle component by heating the region to a heat-up temperature in a temperature range between 500° C. and 900° C.; maintaining the heat-up temperature for a duration of a holding time; and cooling down from the heat-up temperature in one or more phases. A body component constructed as a structural and/or safety-related motor vehicle component from a steel sheet blank that has been hot-formed and press-hardened includes joining flanges and/or coupling locations and/or safety-related parts, wherein the joining flanges, coupling locations and/or safety-related parts are partially heat-treated in several steps with the disclosed method.
