| DIN | 1.2344 | 0.37~0.42 | 0.90~1.20 | 0.3~0.50 | 4.80-5.50 | 1.20-1.50 | 0.90-1.10 | _ | ≤0.03 | ≤0.03 |
Heat treatment
| Hardness | 56-58HRC | – |
| Anneal | 860-890°C | ≤235HB |
| Quenching | 1020-1050°C | Air or oil cooling |
| Tempering | 560-580°C | 47-49HRC, 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. | ||
Applications include:
- Forging dies
- Gripper dies
- Hot press dies
- Extrusion mandrels
- Hot header dies
- Hot work punches
