What’s Application of GB 9CrWMn Mold Steel?
GB/T 1299 9CrWMn steel is a typical alloy Tool steel, Its Cold work Mechanical Properties is very nice. 9CrWMn mold steel with high abrasion resistance, micro deformation of cold work die steel, the wind hard tool steel, carbon content as high as 0.95%, the heat treatment hardness can reach 64 HRC. 9CrWMn steel products can be used to manufacture of small cross-section, and the complex shape of Die, as well as various measuring tools. Commonly used in stamping die, stamping die, bending die, drawing die, punch punch and finishing molds Mould.
