航空用不锈钢种类与冶炼工艺及发展趋势的探讨

Discussion on Variety,Melting Technology and Development Trend of Stainless Steel for Aviation

应用于航空工业的不锈钢品种较多,主要钢种可按用途分为两类：飞机发动机用耐热不锈钢和飞机机体用高强度不锈钢。钢种的来源有纳入国军标的成熟钢种；随引进发达国家机种及技术的优良品种；还有国内冶金、航空系统参考国际先进技术自行研制的创新产品。随着新机种的研发,更多优良的钢种和冶炼工艺将逐步创新脱颖而出。

There are many stainless steel varieties used in aviation industry. The main varieties can be classified as heat - resisting stainless steel for aircraft engine and high strength stainless steel for aircraft body according to their usages. The existing varieties originated from matured ones listed in Chinese national military standard, excellent varieties imported from developed countries together with aircrafts and the related technology and some ones independently developed by Chinese researchers in the fields of metallurgy and aviation by referring to international advanced technologies. It is expected that more and more quality stainless steel varieties and smelting technologies will come forth with the research and development of new type aircrafts.
