Scope

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.
