1.1This specification covers pressure consolidated powder metallurgy iron-nickel-chromium-molybdenum (UNS N08367) and nickel-chromium-molybdenumcolumbium (Nb) (UNS N06625), nickel-chromium-iron alloys (UNS N06600 and N06690), and nickel-chromium-iron-columbium (Nb)-molybdenum (UNS N07718) alloy pipe flanges, fittings, valves, and parts intended for general corrosion or heat-resisting service.
1.1.1UNS N06625 products are furnished in two grades of different heat-treated conditions:
1.1.1.1Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).
1.1.1.2Grade 2 (solution annealed)—Material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required.
1.2UNS N08367 products are furnished in the solution annealed condition.
1.3UNS N06600 products are furnished in the annealed condition.
1.4UNS N06690 products are furnished in the annealed condition.
1.5UNS N07718 products are furnished in the solution annealed + precipitation hardened condition.
1.6The 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.
1.7The 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.
1.8This 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.
