Soft Annealing: Heat to 780-810°C, cool slowly. This will produce a maximum Brinell   hardness of 240.  

Stress Relieving: Stress relieving to remove machining stresses should be carried out by heating to 650°C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening: Harden from a temperature of 1080-1160°C followed by air, oil or warm bath quenching. Hardness after quenching is 47-53 HRC.
