This specification tackles standards for pressure consolidated powder metallurgy iron-nickel-chromium-molybdenum and nickel-chromium-molybdenum-columbium pipe flanges, fittings, valves, and parts intended for general corrosion or heat-resisting service. Compacts shall be manufactured by placing a single powder blend into a can, evacuating the can, and sealing it. The can material shall then be selected to ensure that it has no deleterious effect on the final product. The specimen shall be heated and placed under sufficient pressure for a sufficient period of time to ensure that the final consolidated part is fully dense. The powder shall be produced by vacuum melting followed by gas atomization. The heats shall be thoroughly mixed to ensure homogeneity when powder from more than one heat is used to make a blend. The material shall have the chemical compositions of carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, nickel, iron, cobalt, columbium, aluminum, titanium, nitrogen, and copper. Hydrostatic test shall be conducted and the specimen must show no leaks. The density test shall be performed using sample suspended from a scale and weighed in air and water using Archimede’s principle. Check Analysis shall be wholly the responsibility of the purchaser. The parts of the specimen shall be uniform in quality and condition, and shall be free from injurious imperfections.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.

4.1 The impact resistance of thermoplastic pipe and fittings relates to suitability for service and to quality of processing. Impact resistance may also provide a relative measure of a material's resistance to breakage during handling and installation and, for non-buried applications, to in-service breakage. See Appendix X5 for guidelines for selecting testing combinations.4.2 Results obtained by use of this practice can be used in three ways:4.2.1 As the basis for establishing impact test requirements in product standards,4.2.2 To measure the effect of changes in materials or processing, and4.2.3 To measure the effect of the environment.1.1 This practice covers the determination of the impact resistance of thermoplastic pipe and fittings under specified conditions of impact by means of a tup (falling weight). Three interchangeable striking noses are used on the tup, differing in geometrical configuration. Two specimen holders are described.NOTE 1: Appendix X1 shows the procedure to determine impact strength.1.2 The values stated in inch-pound units are to be regarded as standard.
