Tempering involves reheating the hardened tool/die to a temperature between 150-675°C, depending on the steel type. Heat treatment diagrams are available for a huge number of materials in the Total Materia database. The tempering herewith, in particular as regards the alloying elements Mn and Cr, which • Decarburisation - usually because of insufficient or unequal metal removal during initial machining of “black” billet. A process which controls final properties whilst relieving stresses after hardening, tempering can be complex; some steels must be subjected to multiple tempering operations. • Poor post-heat-treatment practice, such as incorrect grinding or EDM. “area to be kept soft”, “press temper to keep flat”). temperature normally used for tools belonging to this group lies in the That said there is a basic template that is common to all, that is: The hardening of these steels, which are made with carbon contents between 0,80% and 1,20%, is quite straightforward: Since the rate of carbide dissolution proceeds rapidly, the holding time, as a consequence, is short and therefore the heating of small tools can often take place without any extra precautions against atmospheric oxidation. D6 (X210CrW12) DIN 1.2436 AISI D6: 2.10: 12.00: 0.70W: Very high wear resistance and has better hardenability than D3. This allows for accurate and consistent control of case depth during carburising and the decarburising atmosphere for neutral hardening. Any special certification or testing requirements. Sections less Some of the most difficult steels to harden are tool steels. Do remove all “black” and decarburised layers and surface defects - ensure the initial section size is large enough to allow this. Tool steels are furnished in the annealed condition which is the soft, machineable and necessary condition for proper heat treat response. The purpose of hardening is to enable the tool to resist wear and make it hard enough to cut other materials; tempering is carried out after hardening to reduce the brittleness which results from hardening the steel.
