PROPRIETARY SIHARD K770 Heat Treatments
- Soft annealing: Heat to 840-880°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. 650-700°C, holding for minimum 1 hour at heat, followed by air cooling in furnace. This operation is performed to reduce distortion during heat treatment.
Hardening: Harden from a temperature of 1020-1050°C followed by oil, air quenching or warm bath quenching 500-550°C. Hardness after quenching is 62-64 HRC.
