Abstract

The invention relates to a method for producing a metal structural component, in particular a vehicle structural component, in which a steel part is hot formed and is hardened at least over sections by contact with a tool surface, in which the steel part is during the hardening cooled in at least two partial regions at different cooling rates, so that the partial regions after the hardening differ in their microstructure, wherein the cooling rates differing from one another are produced by sections of the tool surface corresponding to the partial regions of the steel part, which differ from one another as regards their thermal conductivities. The invention also relates to a further method for producing a metal structural component, as well as a tool and a batch furnace.
