Abstract (en)
[origin: WO2013087274A1] The invention relates to a method for producing partially-hardened components from steel sheets, in which a component that is cold-formed from a hardenable steel sheet material is heated, in a furnace, to a temperature below the austenitisation temperature (< Ac3), and a radiating element acts upon the component in sections where said component is to be austenitised (< Ac3), this radiating element having a component-side contour that corresponds to the contour of the component in the section to be austenitised. The invention also relates to a device for carrying out said method.
