Heat Treatment Soft Annealing Heat to 710-740°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 230. Stress Relieving Stress relieving to remove machining stresses should be carried out by heating to approx. 650°C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Hardening Harden from a temperature of 830-880oC followed by oil or quenching or warm bath quenching 180-220°C. Hardness after quenching is 51 HRC. Tempering °C 100 200 300 400 500 600 700 HRC 51 50 48 46 42 36 28
