| Quenching | ******0°C | Air or oil cooling |
| Tempering | ******0°C | ****2HRC, 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 *0°C lower than the first one. | ||
