Characteristics
| 1. High hardening ability and abrasion resistance |
| 2. Less quenching deformation |
| 3.Higher toughness and more homogeneous carbide distribution than Cr12 steel |
Applications
Suitable for various complicated cold working dies with high precision and long lifetime, such as punching dies, cold extrusion dies, thread rolling dies, screw plates, cold extrusion dies and precise
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. |
