Abstract (en)
[origin: WO2011141367A1] In a method for producing a structural part from an iron-manganese-steel sheet (1), a sheet-metal workpiece (2) is cold-formed in a forming die (3). The formed sheet-metal workpiece is heated to a temperature between 500°C and 700°C (4) and calibrated in a calibrating die (5).
