Abstract

The invention relates to a process for producing a component having improved elongation at break properties, in which a component is firstly produced, preferably in a hot forming or press curing process, and the component is heat treated after hot forming and/or press curing, where the heat treatment temperature T and the heat treatment time t essentially satisfy the numerical relationship T≥900·, where the heat treatment temperature T is in ° C. and the heat treatment time t is in seconds. The invention also relates to a component, in particular an automobile body component or the chassis of a motor vehicle, which has been produced by such a process. The invention further relates to the use of such a component as part of an automobile body or a chassis of a motor vehicle.
