1.1 本规范 2. 覆盖轧制镍铬钼铌合金（UNS N06625）和镍铬钼硅合金（UNS N06219） 3. 板材、薄板和带材。 1.1.1 UNS N06625合金产品分为两个等级，具有不同的热处理条件: 1.1.1.1 1级（退火）- 材料通常用于高达1100°F（593°C）的工作温度。 1.1.1.2 2级（固溶退火）- 当需要抗蠕变和断裂时，材料通常用于1100°F（593°C）以上的工作温度。 注1: 热加工或重新退火可能会显著改变特性，这取决于工作历史和温度。 1.1.2 UNS N06219合金仅在固溶退火条件下提供。 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/材料的适当材料安全数据表（MSDS）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。 1.4 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 2 covers rolled nickel-chromium-molybdenum-columbium alloy (UNS N06625) and nickel-chromium-molybdenum-silicon alloy (UNS N06219) 3 plate, sheet, and strip. 1.1.1 Alloy 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. Note 1: Hot-working or reannealing may change properties significantly, depending on working history and temperatures. 1.1.2 Alloy UNS N06219 is supplied in solution annealed condition only. 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 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 Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 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.
