Title:
METHOD FOR PRODUCING A STEEL SHEET COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/137910
Kind Code:
A1
Abstract:
The invention relates to a method for producing a steel sheet component (1), comprising the following steps: heating the steel sheet component (1), wherein a first temperature control in a first region of the steel sheet component (1) is predefined such that complete austenitizing is obtained in the first region, and a second temperature control in a second region (3) of the steel sheet component (1) is predefined such that partial austenitization is obtained in the second region (3), deforming a first partial trimming of the steel sheet component (1), wherein the first partial trimming being produced along a first partial length (2) of a predetermined cutting contour and the first partial length (2) extends into the first region of the steel sheet component (1), cooling of the steel sheet component (1), second partial trimming of the steel sheet component (1), wherein the second partial trimming being produced along a second partial length (4) of the predetermined cutting contour and the second partial length (4) extending into the second region (3) of the steel sheet component. The invention also relates to a further method in which a complete austenitisation of the steel sheet component (1) is achieved by heating and an at least partial conversion of austenite into martensite and/or bainite is obtained in the first region and no conversion or partial conversion of austenite into martensite and/or bainite is achieved in the second region as a result of cooling following the deformation of the first partial trimming and following the second partial trimming.
