标准类型的锻造不锈钢的化学成分列于ASTM规范A240中。UNS 20000系列指定镍铬锰耐腐蚀类型，不能通过热处理硬化。UNS 30000系列是镍铬耐腐蚀钢，不能通过热处理硬化。然而，UNS 40000包括可硬化的马氏体铬钢和不可硬化的铁素体铬钢。关于这些类型材料的一般信息和使用，建议参考SAE J412。看 表1 .

The chemical composition of standard types of wrought stainless steels are listed in ASTM Specification A240. The UNS 20000 series designates nickel-chromium manganese, corrosion resistant types that are nonhardenable by thermal treatment. The UNS 30000 series are nickel-chromium, corrosion resistant steels, nonhardenable by thermal treatment. The UNS 40000 however, includes both a hardenable, martensitic chromium steel and nonhardenable, ferritic, chromium steel. Reference to SAE J412 is suggested for general information and usage of these types of materials. See Table 1 .
