摘要 |
<p>The invention relates to a method for producing hardened profiles, in particularly hardened open profiles, wherein the component (1) is at least partly heated to above the austenitising temperature of the base material and after heating the component (1) 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 (1) to adjust a temperature or hardness gradient over the cross section of the component (1),the size type and extension of the edges being set for a desired degree of hardness and/or hardness gradient.</p> |
