Abstract (en)
[origin: WO2010094538A1] The invention relates to a method for producing a press-quenched metal component, in which a sheet bar (2) or a semifinished blank (30, 40, 50, 60) is press-quenched in a forming tool (12), wherein the sheet bar (2) or the semifinished blank (30, 40, 50, 60) has subregions (4, 36) with reduced wall thickness and the subregions (4, 36) with reduced wall thickness are not press-quenched. The invention also relates to a press-quenched metal component of steel or a steel alloy, in particular for a motor vehicle, preferably produced by a method according to the invention, which is not press-quenched in at least one subregion (4, 36), wherein at least one subregion (4, 36) that is not press-quenched has a reduced wall thickness in comparison with the subregions that are press-quenched.
