全国汽车、拖拉机、内燃机镍铬钢代用经验交流会议提出了汽车、拖拉机、内燃机产品主要零件使用钢的决议。我们认为这一决议提出既结合了我国资源的条件,并广泛采用球墨铸铁,是一个很重要的措施。今将这些产品所使用的合金钢公布出来,希有关单位组织学习,为今后汽车、拖拉机、内燃机的生产翻几番创造有利的条件并广泛地试验采用,摆脱镍铬的依赖,并为建立我国的合金钢系统做好准备。 National automobile, tractor, internal combustion engine Ni-Cr steel substitution experience exchange meeting proposed car, tractor, internal combustion engine products, the main part of the use of steel resolution. In our opinion, this resolution proposes that the conditions of our resources should be combined with the extensive use of ductile iron as a very important measure. Now, the alloy steel used for these products is announced, and hopefully the relevant units organize study to create favorable conditions for the future production of automobiles, tractors and internal combustion engines and to widely test and adopt them so as to get rid of the Ni-Cr dependence and to establish a Alloy steel system ready.
