冷作模具钢主要用于制造对冷状态下的工件进行压制成型的模具。如：冷冲裁模具、冷冲压模具、冷拉深模具、压印模具、冷挤压模具、螺纹压制模具和粉末压制模具等。冷作模具钢的范围很广，从各种碳素工具钢、合金工具钢、高速工具钢到粉末高速工具钢和粉末高合金模具钢。冷作模具钢具是真空脱气精炼钢，内质纯净，机械加工性良好，切削明显提高，淬透性良好，空冷淬硬不易出现淬裂，耐磨性极为优异，韧性良好，可用作不锈钢及高硬度材料的冲裁模。
Cold working die steel is mainly used to manufacture the die for pressing the workpiece in cold state. Such as: cold blanking die, cold stamping die, cold drawing die, stamping die, cold extrusion die, thread pressing die and powder pressing die. The range of cold working die steel is very wide, from all kinds of carbon tool steel, alloy tool steel, high speed tool steel to powder high speed tool steel and powder high alloy die steel. Cold working die steel is a kind of vacuum degassing refined steel. It has pure inner quality, good machinability, obvious improvement in cutting and good hardenability. It is not easy to crack in air cooling hardening. It has excellent wear resistance and good toughness. It can be used as blanking die for stainless steel and high hardness materials.
