| AISI | D2 | 1.40~1.60 | 0.10~0.60 | 0.20~0.60 | 11.0~13.0 | 0.70~1.20 | 0.50~1.10 | ≤0.030 | ≤0.030 |
Heat Treatment
| Hardness | 60-64HRC | |
| Anneal | 840-860°C | ≤207-255HB |
| Quenching | 980-1040C | Air or oil cooling |
| Tempering | 510-540°C | 60-64HRC, tempering twice |
| 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. | ||
