冷作模具钢在工作时.由于被加工材料的变形抗力比较大,模具的工作部分承受很冷作模具钢大的压力、弯曲力、冲击力及摩擦力。因此,冷作模具的正常报废原因一般是磨损.也有因断裂、崩力和变形超差而提前失效的。

冷作模具钢与刃具钢相比.有许多共同点。要求模具有高的硬度和耐磨性、高的抗弯强度和足够的韧性,以保证冲压过程的顺利进行、其不同之处在于模具形状及加工艺复杂.而且摩擦面积大.磨损可能性大.所以修磨起来困难。因此要求具有更高的耐磨化模具工作时承受冲压力大.又由于形状复杂易于产生应力集中,所以要求具有较高的韧性;模具尺寸大、形状复杂.所以要求较高的淬透性、较小的变形及开裂倾向性。总之,冷作模具钢在淬透性、耐磨性与韧性等方面的要求要较刃具钢高一些.而在红硬性方面却要求较低或基本上没要求(因为是冷态成形),所以也相应形成了一些适于做冷作模具用的钢种,例如,发展了高耐磨、微变形冷作模具用钢及高韧性冷作模具用钢等。下面结合有关钢种选用进一步说明。
