Trade Lead Description:
Smelting:
- Components: high hardenability, good wearing resistance, good oxidation resistance of high temperature and high anti-rust.
- Technic: EAF+LF+VD+ESR, produced high purity and good performance steels.
Heat Treatment:
- Anneal: 840-860℃, Hardness: 207-255HB
- Quenching: 980-1040℃, oil cooling or air cooling
- Tempering: 510-540℃, and tempering twice
- Hardness: 60-64HRC
- High temperature oxidation resistance, high anti-rust after quenching and polishing, light deform under heat treatment.
- Hot hardness will increase after twice hardening, which will be proper for those molds worked under 400-500℃ or needed nitriding treatment.
