1.1 本规范 2. 涵盖了通过热轧和控制冷却生产的奥氏体高锰合金钢板。这些板材主要用于焊接压力容器。 1.2 由于轧制和冷却过程的固有特性，或两者兼而有之，板材不得在超过932°F[500°C]的温度下成型。 1.3 板材的最大厚度仅受材料满足规定机械性能要求的能力的限制；然而，目前的工厂惯例通常将这种材料限制在最大2.5英寸[63.5毫米]。 1.4 以英寸-磅单位或国际单位表示的值应单独视为标准值。在文本中，国际单位制显示在括号中。每个系统中所述的值不是完全等效的；因此，每个系统都必须独立使用。结合两个系统的值可能会导致不符合规范。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 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 austenitic high-manganese alloy steel plates produced by hot rolling and controlled cooling. The plates are intended primarily for use in welded pressure vessels. 1.2 Due to the inherent characteristics of the rolling and cooling processes, or both, the plates shall not be formed at temperatures exceeding 932 °F [500 °C]. 1.3 The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements; however, current mill practice normally limits this material to 2.5 in. [63.5 mm] max. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.5 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. 1.6 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.
