1.1 本规范 2. 包括沉淀硬化不锈钢板、薄板和带材。这些钢的机械性能是通过适当的低温热处理（通常称为沉淀硬化）来发展的。 1.2 这些钢用于在室温或高达600的温度下需要耐腐蚀性和高强度的零件 °F（315 °C）。这些钢中的一些特别适合在固溶处理条件下进行中度至重度拉伸和成形。其他的只能温和地形成。它们适合在固溶退火条件下进行机加工，之后可以硬化至本标准中规定的机械性能，而不会有破裂或变形的危险。 1.3 以英寸表示的值- 磅单位应视为标准。 1.4 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 2 covers precipitation-hardening stainless steel plate, sheet, and strip. The mechanical properties of these steels are developed by suitable low-temperature heat treatments generally referred to as precipitation hardening. 1.2 These steels are used for parts requiring corrosion resistance and high strength at room temperature or at temperatures up to 600 °F (315 °C). Some of these steels are particularly suitable for moderate to severe drawing and forming in the solution-treated condition. Others are capable of mild forming only. They are suitable for machining in the solution-annealed condition, after which they may be hardened to the mechanical properties specified in this standard without danger of cracking or distortion. 1.3 The values stated in inch-pound units are to be regarded as the standard. 1.4 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.
