Cr_4W_2MoV是一个符合我国自然资源的新钢种,用于加工制造冷模具等以代替Cr_(12)类钢。我厂自75年组织了工人、干部、技术人员参加的三结合试用小组在华中工学院实践队同学和老师的配合下选定了近十种原用Cr_(12)制造的,且消耗较大的自行车工模具从锻打、退火、机械加工热处理和化学热处理一直到生产使用、寿命考核进行了试验。对用Cr_4W_2MoV钢制造的比较典型的
Cr_4W_2MoV is a new type of steel that conforms to China’s natural resources and is used to manufacture cold molds instead of Cr_ (12). Since 1975, our factory has organized three combined trial groups with workers, cadres and technical staff to participate in the selection of nearly ten kinds of original Cr_ (12) manufactured by Huazhong Institute of Technology practice team of students and teachers, and consumed more Bicycle tool from forging, annealing, machining heat treatment and chemical heat treatment until the production and use, life assessment conducted a test. For the typical steel made of Cr_4W_2MoV
