Introduction of D2 cold working die steel

       D2 cold working die steel D2 is a widely used high carbon and high chromium cold working die steel, which has high wear resistance, hardenability, hardenability, micro deformation, high thermal stability and high bending strength; D2 can be used to manufacture some cold work die steel with large cross-section, complex shape and high wear resistance, which is suitable for manufacturing high-precision and long-life cold working die, such as complex shape punching die and cold extrusion die The machine has the advantages of high precision, high precision and high precision.
