Beschreibung
Zusammenfassung:	A method for producing a component by forming a plate from steel at room temperature having a high formability and reduced crack sensitivity of edges that have been mechanically cut or punched on the plate, includes: cutting the plate from a strip or metal sheet at room temperature; heating edge regions of the plate that underwent strain hardening as a result of the cutting step to a temperature of at least 600° C. for a time period of at most 10 seconds; and forming the plate in one or more steps into a component at room temperature, wherein in the forming step the edge regions heated in the heating step are subjected to cold forming.
