Mold steel can be roughly divided into cold work mold steel, hot work mold steel and plastic mold steel. Due to the different uses of the various molds and the complicated working conditions, the steel used for the molds should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability and hardening according to the working conditions of the molds it manufactures. Hardness and other process performance. Due to the different uses of this type and the complicated working conditions, the performance requirements for the steel used in the mold are also different.
The die just includes cold die, wire drawing die, drawing die, stamping die, thread rolling die, thread rolling plate, cold heading die and cold extrusion die. Cold work molds have steel, and according to the working conditions they are manufactured, they should have high hardness, strength, wear resistance, sufficient toughness, and high rate permeability, rate hardness and other process properties.
