CrWMn钢用于手表生产中的小型模具,由于存在阜期崩刃问题,一般使用寿命低。如果提高回火温度,降低硬度,则易于冲塌和磨损。根据材料科学近期成果,得知低碳马氏体具有优良的强韧性,但是多数报导都是用 CrWMn steel for the production of small watches in the mold, due to the existence of the collapse of the issue of the period, the general service life is low. If you increase the tempering temperature, reduce the hardness, it is easy to crash and wear. According to the recent achievements of material science, it is known that low-carbon martensite has excellent toughness, but most reports use
