Heat Treatment Instruction

Treatment Temperature Range Cooling/Quenching Notes
Forging 1700-2100° F Slow. Cool slowly in dry sand or in other insulating media.
Annealing 1600-1650° F Cool slowly at a rate of 35° F per hour to 1000° F. For best results, insulating media is desirable. Hold at temperature for 2 hours.
Stress Relieving 1100-1300° F Cool slowly Stress relieve after rough machining
Preheating 1500-1550° F   Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible.
Hardening 2325-2375° F (furnace) 2275-2350° 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 2375° F. For maximum toughness and high hardness, harden at 2275° F.
Tempering (See Chart)   Double tempering is recommended. The usual tempering time is 2+2 hours. Recommended temperature is 1000-1075° F for cutting tools. 1100-1200° F for shock tools
