高温用锻制或轧制合金钢和不锈钢法兰、锻制管件、阀门和部件1

本标准发行所采用的代号A182/A182M是固定的，标准代号后紧跟的数字代表着首版年份或最近一次修订的年份（如果修订）。括号中的数字代表最近一次审批的年份。用字母（c）做上标表示自上次修订或重新审批之后做了编辑上的修订。

本标准已经国防部批准使用。

1.范围

1.1 本标准2适用于压力系统使用的锻制低合金钢和不锈钢的管道部件，其中包括法兰、管件、阀门和相似零件，它们符合规定尺寸或尺寸标准（如第2章引用的ASME标准）。1.2 棒材和由棒材直接加工成的产品（而非本规范中直接提出的那些材料，见6.4），参照规范A479/A479M和A739中适用的类似的牌号。依据本标准制造的产品限制其最大重量为10000 Ib（4540kg）。对于较大产品和其他用途的产品参照规范 A336/A336M和A965M 中适用的类似铁素体和奥氏体牌号。

1.3 本标准中包括若干牌号的低碳合金钢和铁素体、马氏体、奥氏体和铁素体-奥氏体不锈钢。应根据设计和使用要求来选用。在标准A1049/A1049M中同样也包括了很多铁素体/奥氏体（双相）牌号。

1.4 当要求附加试验或检查时，提出补充要求供使用。这些只有买方在定单中逐一规定时才使用。

1.5 本规范以英寸-磅及SI单位表示。然而，除非在定单中规定采用“M”规范表示（SI制单位），否则材料将以英寸-磅单位供应。

1.6 以英寸-磅单位或以SI单位表示的数值分别都认作为标准。在本标准中，SI单位的数值用括号表示。两种单位制的数值并不完全相等，所以每种单位制都必须单独使用。两种单位制的混合使用会导致与本规范的不一致。
