冷作模具钢及其热处理方法

Cold Work Die Steel and Their Heat Treatment Method

冷作模具钢用于制造使金属在冷态下变形的模具，如冲裁模、拉丝模、弯曲模、拉深模等，有时还用于制造其他工具（如剪刀片等）。这类模具工作时的实际温度一般不超过200—300℃。由于冷作模具钢在加工过程中会受到较大的冲击力和摩擦力作用所以工作环境相对恶劣，就需要对它进行特定的热处理以改善其性能，使其达到最好的使用效果。

Cold work die steel used in the manufacture of the metal under the cold deformation of the mold, such as blanking die, drawing die, bending die, drawing die, etc, sometimes used in the manufacture of other tools （such as scissors, etc.）. Actual temperature of this kind of mold work is generally not more than 200-300℃. Due to cold work die steel in the machining process will be affected by the larger impact force and friction force effect so the work environment is relatively bad, you need to specific heat treatment to improve its performance, to the best use effect.
