1.1 本规范涵盖用于一般腐蚀或耐热服务的压力固结粉末冶金镍合金管法兰、配件、阀门和零件。 1.1.1 UNS N06625产品提供两种不同热处理条件的等级: 1.1.1.1 1级（退火）-材料通常在高达1100的工作温度下使用 华氏度（593 °C）。 1.1.1.2 2级（固溶退火）-材料通常在高于1100的工作温度下使用 华氏度（593 °C）当需要抗蠕变和断裂时。 1.2 UNS N08367产品在固溶退火条件下提供。 1.3 UNS N06600产品在退火条件下提供。 1.4 UNS N06690产品在退火条件下提供。 1.5 UNS N07718产品在固溶退火+沉淀硬化条件下提供。 1.6 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。 1.7 以下安全危险警告仅适用于试验方法部分、章节 7.3 和 13 ，本规范: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.8 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 pressure consolidated powder metallurgy nickel alloy pipe flanges, fittings, valves, and parts intended for general corrosion or heat-resisting service. 1.1.1 UNS N06625 products are furnished in two grades of different heat-treated conditions: 1.1.1.1 Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100 °F (593 °C). 1.1.1.2 Grade 2 (solution annealed)—Material is normally employed in service temperatures above 1100 °F (593 °C) when resistance to creep and rupture is required. 1.2 UNS N08367 products are furnished in the solution annealed condition. 1.3 UNS N06600 products are furnished in the annealed condition. 1.4 UNS N06690 products are furnished in the annealed condition. 1.5 UNS N07718 products are furnished in the solution annealed + precipitation hardened condition. 1.6 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. 1.7 The following safety hazards caveat pertains only to test methods portions, Sections 7.3 and 13 , of this specification: 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and to determine the applicability of regulatory limitations prior to use. 1.8 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.
