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&#xb0; C. and 900&#xb0; 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.

Method for producing a motor vehicle component, and a body component

A hot forming line for producing hot formed and press hardened steel sheet products, includes: a forming device; a heating device having a temperature treatment station, wherein the temperature treatment station includes an upper tool and a lower tool, and at least one temperature treatment source; and exchangeable temperature treatment plates for conductive temperature treatment of a blank or part inserted into the temperature treatment station, wherein the exchangeable temperature treatment plates are constructed for arrangement on the upper tool and/or the lower tool, and the temperature treatment source is constructed for heating or cooling the temperature treatment plates. The temperature treatment station is constructed for treating different regions of the blank or part with different temperatures by conductive contact of the temperature treatment plates with the blank of part.

Hot forming line and method for producing a hot formed and press hardened motor vehicle part

A blank cut from a strip of hardenable hot-formed steel is heated in a furnace to a temperature which is smaller than an Actransformation point in an iron carbon diagram. A first region of the blank is then heated in a conductive heating station to a temperature above the Actransformation point and subsequently hardened in a hot forming and hardening tool to produce a steel part with at least two microstructured regions of different ductility.
