1.1 本规范涵盖了更常用类型的不锈钢自由加工钢中的热加工或冷加工板、薄板和带材，这些钢是专门为最佳可加工性以及一般腐蚀和高温服务而设计的。不锈钢和耐热板、薄板和带材（自由加工类型除外）包含在单独的规范中。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification covers hot-finished or cold-finished plate, sheet, and strip in the more commonly used types of stainless free machining steels designed especially for optimum machinability and for general corrosion and high temperature service. Stainless and heat-resisting plate, sheet, and strip, other than free-machining types, are covered in separate specifications. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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.
