According to the use of die steel can be divided into three categories:
1. cold die steel
2. hot die steel
3. plastic die steel.
Characteristic:
Cold die steel on hardness wear resistance of high carbon and alloy elements to increase hardenability, improve wear resistance.
The appropriate requirements of hot die steel on hardness, red hardness, wear resistance and thermal conductivity, low carbon content, alloying elements to increase hardenability, improve the wear resistance of rigid red.
Plastic mould steel corrosion resistance wear resistance of thermal fatigue resistance is good, the hardness of the material. The uniform polishing performance, low impurity content. The production cycle stability. Kunshan cold die steel
