CrWMn die steel plate is alloy tool steel, oil quenching low deformation cold working die steel.The steel wearability

CrWMn die steel plate is alloy tool steel, oil quenching low deformation cold working die steel.The steel wearability, due to join the mass fraction of 1.20% ~ 1.60% of tungsten, form carbides so after quenching and low temperature to have ⼀hardness and abrasion resistance.Tungsten helps to keep fine grains from making steel more pliable.The steel is sensitive to forming carbon, which may cause the blade to spalling.Although the strength, hardness and toughness of the steel are higher than that of the carbon steel, it has defects such as easily cracking and grinding cracking due to carbide segregation.The quenching tends to carbon steel, and the application range is reduced.The hardenability and abrasion resistance of the steel as well as the hardness of chromium steel and chromium silicon steel after quenching are good, and the toughness is good.
CrWMn mainly used for carbon tool steel can not meet the requirements of large cross section, more complex shape of die parts, require less quenching deformation
