SS 23 12 Heat Treatments
- Soft annealing: 850°C, holding time approx. 2 hours after heating. The steel is protected against decarburization and oxidation. Cooling 10°C / h to approx. 600°C, then free cooling in air.
Relaxation annealing: 600 - 700°C, holding time approx. 2 hours after heating. Cool in the oven to about 500°C, then free cooling in air.
Hardening: Preheating to 500 - 800°C. Curing temperature 940 - 990°C, normally 970°C. Cooling in oil, stage bath or air. Tempering immediately after cooling to approx. 50°C. The surface hardness achieved after curing is relatively independent of dimension and coolant.
Tempering: The temperature is selected with regard to the desired hardness based on the tempering diagram. Tempering twice with intermediate cooling to room temperature is recommended. The effect of time on the hardness at tempering temperatures below 500°C is relatively small, but increases with rising temperature.
