1, Chemical Composition
Element | C | Si | Mn | Cr | Mo | Ni | P | S |
content | 0.4~0.6 | ≤0.4 | 0.5~0.8 | 0.5~0.8 | 0.15~0.3 | 1.4~1.8 | ≤0.03 | ≤0.03 |
2, Feature
1 good tenacity, toughness and high wear resistance. It have the same mechanical property in both room temperature and 500~600°C
2 when it is heated to 500°C, it can still maintain hardness at HB300
3 Excellent hardenability, less sensitive to termper brittleness.
4 good bearing capacity and heat intensity.
3, Applications
For making large hammer forging die with complex shape and high shock load
4. Sizes
