Heat treatment:
l FORGING:forming temperature: 1100-850℃
l SOFT ANNEALING: Heat to 730-760℃, cool slowly. This will produce a maximum Brinell hardness of 207.
l STRESS RELIEVING: Stress relieving to remove machining stresses should be carried out by heating to approx. 600-650℃, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
l HARDENING: Harden from a temperature of 780-810℃, 820-850℃ followed by water or oil quenching. Hardness after quenching is about 60 HRC.
l TEMPERING: Tempering temperature: 150-180℃.
