含铌低合金钢在武钢的研制与发展

Research and development of low alloy steels containing Nb in WISCO

回顾了含铌低合金钢在武钢研制开发的历史进程,总结了武钢铌微合金化技术近30年来的成功经验,介绍了武钢含铌管线用钢、桥梁用钢、压力容器用钢、工程机械用钢的研究与应用状况。此外,简要介绍了武钢生产装备水平逐年提高,促进含铌低合金钢综合性能大幅改善的情况。

The progress of research and development on low alloy steels containing Nb in Wuhan Iron and Steel Corporation（WISCO） is briefly reviewed in this paper.Successful practice in developing Nb micro-alloyed steels in the last 30 years is summarized with emphasis on the research and application of pipe-line steels,bridge steels,pressure vessel steels and machinery steels which are alloyed using microelement Nb.The properties of steels containing Nb have been obviously improved year by year due to the upgrade of steel and rolling production facilities in WISCO.
