Features
Smelting:
- Components: high hardenability, good wearing resistance
- Technic: EAF+LF+VD, produced high purity and good performance steels.
Heat Treatment:
- Anneal: 820-880°C, Hardness: ≤229HB
- Quenching: 1010-1030°C, fast cooled
- Tempering: 550-650°C, tempering three times and will not commend to temper in highest temperature.
- Hardness: 43-53HRC
- High hardenability and section below 400mm can harden completely; the good hardness and wearing-resistance can be maintained even at 300-400°C.
- The melting point of this steel is low, so the heating temperature cannot be too high.
- The thermal conductivity is poor and it must be heated slowly.
- It needs to be cooled slowly after forging, which is to avoid cracking.
- It can be put into the pit used for preheating and it can be annealed while it is cooled to 400-500°C.
- Normally tempering three times and each time about 1 to 1.5 hours.
Advantages and Applications
1. Advantages
- Good hardenability;
- Good wearing-resistance;
2. Applications
It is widely used in manufacturing cold-punching molds, punches, cold shear knives
(shearing hard and thin metals, such as silicon steel sheet), drill sleeve, gauges, thread rolling dies, coining dies, screw plates and drawing dies etc., which are small impact load, high wearing-resistance.
