Abstract:
1. A method for producing a metal structural component, for use as a vehicle structural component, comprising the steps of: forming a steel part; hardening the steel part at least over sections by contact with a tool surface; and wherein the step of hardening includes the step of cooling the steel part in at least two partial regions with cooling rates differing from one another, so that the at least two partial regions differ after the step of hardening as regards their microstructure and wherein the cooling rates differing from one another are produced by at least two sections of the tool surface, corresponding to the at least two partial regions of the steel part, that differ from one another in their thermal conductivities, wherein at least one of the at least two sections of the tool surface has been coated so as to provide a surface coating that reduces or increases the thermal conductivity.
