HEAT TREATMENT AND PROCESSES
Heat treatment
| Process | Details |
|---|---|
| Soft Annealing | Heat to 780-820°C, cool slowly in furnace. Maximum Brinell hardness: 255. |
| Stress Relieving | Heat to 600-650°C, hold for 1 hour, followed by air cooling. Reduces distortion during heat treatment. |
| Hardening | Heat to 1170-1220°C, followed by oil or air quenching, or warm bath (550-220°C). |
| Tempering | Temper at 520-550°C, at least twice for at least 62 HRC. |
