Grade: QCM8 
 Standard: Japan - Sanyo 
 Properties and uses: 
 Japanese steel, cold work die steel, the steel is the product of the combination of SKD11 and high-speed steel substrate containing rarely eutectic carbides, or small particles. With excellent wear resistance, good hardenability and heat treatment distortion. 

 Application examples: 
 1, the steel can be applied to fine red mold, forging mold, cold extrusion die, drawing die, curling mold, molding roll. 
 2, can also be used in wear-resistant plastic mold. 
 3, the steel SKD11 steel has the same price, but three times higher than the life of metal mold the SKH51 high-speed steel.
