1、Stainless steels contain from 10 to 30% chromium. Varying amounts of nickel, molybdenum, copper, sulfur, titanium, niobium, etc. may be added to obtain desired mechanical properties and service life. Stainless steels are primarily classified as austenitic, ferritic, martensitic, duplex or precipitation hardening grades. The first stainless steel grades that were commercially produced in the United States were similar to 302, 410, 420, 430, and 446. These five alloys were produced and marketed prior to 1930. In subsequent years, the grades similar to 303, 304, 316, 321, 347, 416, and 440 were brought to market 考虑到腐蚀因素，往往要选择使用不锈钢材料。不锈钢有五个基本的种类: 奥氏体铁素体马氏体双相不锈钢沉淀硬化型不锈钢。 奥氏体不锈钢没有磁性，具有代表性的钢种是加入18%的铬并含有一定的镍， 它们是广泛运用的钢种。铁素体具有磁性，铬元素是其主要的含量，比例为17%，这种材料具有很好的抗氧化性。 马氏体不锈钢同样也具有磁性，铬的含量通常为13%，并含有适量比例的碳，它们可通过淬火和回火而被硬化。双相不锈钢具有铁素体和奥氏体的混合，铬的含量在18%到28%之间，镍的含量4.5%- 8%之间，它们沉淀型不锈钢铬的常规含量17，并加有一定量的镍铜和铌，它们可通过析出和时效被硬化。 表I 世界各国常用不锈钢标准对照表 Chinese U.S.A. ?Germany? ?Italy Japan? ?Russia Sweden ?U.K.?
