Heat Treatment
Hardening: 2100-2190° F/salt, oil or atmosphere quench to 1000-1100° F, equalize, then air cool to below 125° F or hand warm. Vacuum or atmosphere quench rate through 1850-1300° F range critical to achieve optimum heat treat response. Standard recommendation to achieve HRC 68/68 is to use 2175° F.
Tempering: 1000° F minimum recommended. Triple tempering is required.
