摘要：
The invention relates to a method for producing hardened profiles, in particular hardened open profiles, wherein the component is at least partly heated to above the austenitizing temperature of the base material and after heating the component is cooled at a rate above the critical hardening rate, the energy necessary for the heating being introduced at least partly by induction, wherein free edges are provided in the component to adjust a temperature or hardness gradient over the cross section of the component, the size, type and extension of the edges being set for a desired degree of hardness and/or hardness gradient.
