1.1 本规范涵盖各种结构、压力容器、磁性、低温和耐热应用中退火和通常要求的冷加工条件下的奥氏体不锈钢。 1.2 本规范的应用或本规范涵盖的材料的使用不会自动允许在压力容器应用中使用。只有ASME规范特别批准等级的退火条件才允许用于压力容器。 1.3 本规范以英寸磅单位和国际单位制表示；但是，除非采购订单或合同规定了适用的 M 规格名称（国际单位制），应采用英寸磅单位。以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。 将两个系统的值合并可能导致不符合标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers austenitic stainless steels in the annealed and normally required cold-worked conditions for various structural, pressure vessel, magnetic, cryogenic, and heat-resisting applications. 1.2 The application of this specification, or the use of material covered by this specification does not automatically allow usage in pressure vessel applications. Only annealed conditions of grades specifically approved by the ASME code are permitted for pressure vessel use. 1.3 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
