The invention relates to a method for shaping sheet steel. In said method, a blank is produced from the sheet steel, the blank is inserted into a shaping tool, and the shaped workpiece is produced from the blank in a one-stage process by means of the shaping tool. Before being shaped, the blank is heated to such a degree that the steel does not undergo any phase transition and the blank is shaped in the ferritic, pearlitic, or bainitic range without exceeding the eutectoid temperature or the recrystallization temperature. The invention also relates to an apparatus for carrying out said method. |
