| Anneal | 830-870°C | ≤255HB |
| Quenching | 950-980°C | Air or oil cooling |
| Tempering | 180-200°C | 60-62HRC, tempering once |
| It is annealed before ex-factory, which ensure good metallographic structure, proper hardness and good workability. There is no need to anneal again. | ||
| But It must be re-annealed if reforged, as the original organization and performance are destroyed after reforged, and the forging stress increased. | ||
| Normally it will be annealed twice and the temperature of the second annealed is 20°C lower than the first one. | ||
