Heat Treatment
Hardening: 2175-2200° F (furnace) 2150-2175° F (salt bath)/Quench in air or warm oil. To minimize quenching strains, quench in salt at 1000° F. For maximum wear resistance, harden at 2200° F. For maximum toughness and high hardness, harden at 2150° F.
Tempering: Double temper when using tempering temperature above 1000° F. Triple temper when using tempering temperatures below 1000° F. Recommended temperature is 950-1075° F.
