Heat Treatment
Hardening: 2150-2250° F (furnace) 2150-2225° 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 2250° F. For maximum toughness and high hardness, harden at 2150° F.
Tempering: Double tempering is recommended. The usual tempering time is 2+2 hours. Recommended temperature is 1000-1150° F.
