What should be paid attention to in the selection of cold working die steel? Reasonable selection of cold working die steel material, precise forming and proper heat treatment can effectively improve the service life of the die. There is a very important part of the cold work die steel material selection knowledge, next small braid everyone to understand in detail.

例如，对于形状简单，不易变形，截面不大，承受载荷较轻的冷作模具，常选用抚顺特钢9CrWMn、T10等制造；对于形状复杂，容易变形，截面较大，承受载荷较大的冷作模具，宜选用高耐磨模具钢Cr12、Cr12MoV、抚顺特钢SKD11等制造；对于承受大冲击载荷的冷作模具，常选用冲击韧性较高的模具钢，如抚顺特钢DC53、D2等制造。在选用模具材料时，往往需要考虑生产批量。生产批量小或中等的，常选用碳素工具钢或高碳低合金模具钢；而生产批量大，则选用高耐磨模具钢。

For example, Fushun Special Steel 9crwmn and T10 are often used for cold working dies with simple shape, not easy to deform, small cross-section and light load bearing; high wear-resistant die steels Cr12, Cr12MoV and Fushun Special Steel SKD11 should be selected for cold working dies with complex shape, easy deformation, large cross-section and large load bearing capacity; for cold working dies with large impact load, such as Cr12, Cr12MoV and SKD11, etc Die steels with high impact toughness, such as Fushun Special Steel DC53 and D2, are selected for manufacturing. When selecting die materials, it is often necessary to consider the production batch. Carbon tool steel or high carbon low alloy die steel is often used for small or medium-sized production, while high wear-resistant die steel is used for large-scale production.

鉴于冲头与凹模的工作条件和使用性能要求存在着差别，所选用的钢材也有所不同。例如冷挤压钢件和硬铝件时，凹模常选用Cr12、Cr12MoV模具钢；为了延长冲头的使用寿命，则可选用抚顺特钢M2、SKH-9高速工具钢等。

In view of the differences in working conditions and performance requirements between punch and die, the steel used is also different. For example, when cold extruding steel parts and duralumin parts, Cr12 and Cr12MoV die steel are often used for female die; in order to prolong the service life of punch, Fushun Special Steel m2 and skh-9 high-speed tool steel can be selected.
