Soft Annealing of 1.7701
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress Relieving of 1.7701
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening of 1.7701
Harden from a temperature of 800-820oC, 830-850oC followed by water or oil quenching. Hardness after quenching is 64-67 HRC.
Tempering of 1.7701
Tempering temperature: 200-600oC.
Tempering Temperature (oC) vs. Hardness (HRC)
100oC | 200oC | 300oC | 400oC |
