Cold Work Mold Steel is a type of steel used for manufacturing molds that perform forming processes such as stamping, bending, drawing, shearing, cold heading, and cold extrusion on metallic or non-metallic materials at room temperature or lower temperatures.
High Hardness and High Wear Resistance
Cold work mold steel requires high hardness (typically between HRC 58-64) and excellent wear resistance to withstand friction and wear between the mold and the material during operation, ensuring a long service life for the mold.
High Strength and Compressive Resistance
Molds are subjected to significant pressure and impact forces during operation. Therefore, cold work mold steel needs to possess high strength and compressive resistance to prevent deformation or fracture of the mold.
Good Toughness
Despite the need for high hardness, cold work mold steel must still exhibit a certain level of toughness to avoid brittle fracture under impact loads.
Excellent Hardenability
Cold work mold steel needs to have good hardenability to ensure uniform hardness and microstructure throughout the mold during the quenching process.
Dimensional Stability
The mold should minimize deformation during heat treatment to ensure dimensional accuracy and shape stability.
Good Machinability
The steel should possess good cutting and grindability to facilitate the machining and finishing of the mold.
Fatigue Resistance
Molds are subjected to cyclic loading during prolonged use, so they need to exhibit good fatigue resistance to extend the service life of the mold.
