PROPRIETARY SIHARD 2721 Heat Treatments
- Soft annealing: Heat to 610-650°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
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 840-870°C followed by air or oil quenching or warm bath quenching 180-220°C. Hardness after quenching is 59 HRC.
