The difference between cold work mold steel and hot work mold steel

Cold work mold steel is mainly used to make cutting die (such as blank punching die, trim die, punch, and scissors), cold die and cold extrusion die, bending die and drawing die, etc. For the mold steel is mainly focused on hardness, wear resistance. With high carbon content, alloying elements increase hardenability and improve wear resistance. The hot work mold is mainly hammer forging die, hot extrusion die and die casting die.

Hot work die steel requires appropriate hardness, focusing on red hardness, thermal conductivity, and wear resistance. The main feature of working conditions of hot work molds is that they are in contact with the hot metal. Therefore, the carbon content is low, and the alloying elements increase the hardenability and increase the wear resistance and red hardness.
