Abstract:
The present invention relates to a manufacturing process of a structural component for a motor vehicle, wherein a plate bar is heated, is fed to a die in the heated state and is shaped in the die. The process is characterized in that the plate bar is subjected to a nitriding process before the shaping. Furthermore, a plate bar for hot-forming for manufacturing a structural component for a motor vehicle is described, wherein the surface of the plate bar has a nitrided layer. Finally, the present invention relates to a structural component of a motor vehicle, which is manufactured by hot forming from a plate bar having a nitrided layer.
