PROPRIETARY Ravne 880 Heat Treatments
- Soft annealing: Heat to 800 - 830°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 300.
Stress relieving to remove machining stresses should be carried out by heating to 600 - 650°C, holding for one hour a heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening from a temperature of 1250 - 1280°C followed by salt bath or thermal quenching or warm bath approx. 550°C.
Tempering temperature: 550-590°C
