Traitement thermique
Recuit de mise
Tempeacuterature (degC) 710 - 750 Slow controlled cooling in furnace at a rate of 50 to 68degFhr (10 to 20degChr) down to approx 1112degF (600degC) further cooling in air
Stress relieving
Tempeacuterature (degC) 650 Slow cooling in furnace Intended to relieve stresses set up by extensive machining or in complex shapes After through heating hold in neutral atmosphere for 1-2 hours
Trempe et revenu
Tempeacuterature (degC) 780 - 820Oil Salt bath 392 to 482degF (200 to 250degC) up to 0787 inch (20 mm) thickness Holding time after temperature equalization 15 to 30 minutes After hardening tempering to the desired working hardness see tempering chart
