摘要
SNCM630相应的国产牌号为30Cr3Ni3Mo。通过优化30Cr3Ni3Mo钢热处理工艺,其力学性能满足SNCM630材料的要求。30Cr3Ni3Mo钢的国产化成功,不仅解决了依赖成品进口的问题,降低了机组的制造成本,同时为我国螺栓用钢增加了一个新的牌号。
Corresponding domestic designation for SNCM630 is 30Cr3Ni3Mo. By optimizing heat treatment process for 30Cr3Ni3Mo steel, and its mechanical properties conform to the requirements for material SNCM630. Success of domestic research for 30Cr3Ni3Mo steel not only solved the problem of dependence on imported products, but also reduced manufacturing cost of units, and added a new designation to Chinese bolt steel.
