 6CrMnNiMoVWSi steel features: 

 6CrMnNiMoVWSi steel referred to as DS, the new low-alloy cold work tool steel, high toughness, excellent process performance and high life. Its performance is higher than CrWMn, Cr12MoV and 6CrW2Si die steel, which is the development of low-alloy cold work tool steel, high impact toughness of cold-resistant tool steel, the hardenability of steel is good, quenching temperature is lower, heat deformation small , strong toughness, wear resistance and appropriate. Low prices, has good strength and toughness with good impact resistance and. 

 Increase in chromium and manganese steel to improve hardenability can make steel after quenching and tempering to retain a certain amount of residual austenite, reduce distortion; adding silicon and nickel matrix can toughening and tempering to improve resistance, in the same hardness, higher than other similar strength and toughness of steel, molybdenum or vanadium can be refined by adding grain. The steel quenching and tempering after high strength and toughness, impact toughness 210J/CM2, impact toughness than 6CRW2SI tool steel. 

 Typical applications: 

 Used scissors, stamping, cold heading, cold punching die, etc.. Used in the manufacture of high precision and complex tooling.
