Physical properties (averagevalues) at ambient temperature:
Density [g/cm³]: 7.74
Soft annealing
Heat to 770 to 800°C, cool slowly in furnace, this will produce maximum brinell hardness of 229
Stress relieving:
Stress relieving to remove machining stresses should be carried out by heating to 650, holding for 1hours at heat, followed by air cooling, this operation is performed to reduce distortion during heat treatment
Hardening:
Harden from temperature of 880 to 920°C, followed by oil quenching, hardness after quenching is 63 HRC
Forging:
Hot forming temperature: 1050 to 900°C
