1.1 本规范涵盖热加工或冷加工棒材，但用于重新加工的棒材除外( 注1 ). 它包括圆形、方形和六边形，以及热轧或挤压成型的形状，如更常用类型的不锈钢中的角、三通和通道。自由加工类型( 注2 )一般耐腐蚀性和高温服务在单独的规范中涵盖。 注1: 有关重新折叠的钢筋，请参见规范 A314 . 注2: 对于专为优化可加工性而设计的自由加工不锈钢棒，请参阅规范 582/A582米 . 注3: 标准涵盖高镍、铬、奥氏体腐蚀和耐热合金材料。这些标准由ASTM小组委员会B02.07管辖，可在 ASTM标准年鉴 ，第02.04卷。 1.2 以国际单位制或英寸磅单位表示的数值应单独视为标准。在正文中，国际单位制显示在括号中。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。英寸磅单位应适用，除非订单中规定了本规范的“M”名称。 1.3 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 hot-finished or cold-finished bars except bars for reforging ( Note 1 ). It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types ( Note 2 ) for general corrosion resistance and high-temperature service are covered in a separate specification. Note 1: For bars for reforging, see Specification A314 . Note 2: For free-machining stainless bars designed especially for optimum machinability, see Specification A582/A582M . Note 3: There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards , Vol. 02.04. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. 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.
