在鋼鉄发展史上,耐热鋼是个最年輕的領域,它的兴起只是木世紀三十年代的事。但是,在短短二十余年里,无論在鋼种的研究和創制上,还是在理論的探討和闡述上,都获得了不少成就。特別是近十年来发展尤为迅速。可以預料,它将在国民经济中占据日益重要的地位。耐热鋼的应用范围很广,在动力工业、航空工业和許多尖端技术設备上都是不可缺少的。从热机原理看,机械的工作溫度越高則热效率越大。近年来也正向着这方面发展,但这往往决定于耐热材料的发展。高温使用的金属材料除耐热鋼外,还有铁基、鎳基、銅基等耐热合金,它們在成分上与耐热鋼有或
Heat-resistant steel is the youngest area in the history of steel 鉄 and its rise is only a matter of the 1930s. However, in just over 20 years, many achievements have been made both in the research and creation of steel grades and in theoretical discussions and elaboration. In particular, the development has been particularly rapid in the past decade. It can be expected that it will occupy an increasingly important position in the national economy. Heat-resistant steels are used in a wide range of applications and are indispensable in the power industry, the aerospace industry and many cutting-edge technology equipment. From the heat engine principle, the higher the working temperature of the machine, the greater the thermal efficiency. In recent years, this area is also developing, but this often depends on the development of heat-resistant materials. In addition to heat-resistant steel used in high temperature metal materials, there are iron-based, nickel-based, copper-based heat-resistant alloys, which are in the composition and heat-resistant steel or
