ASTM B983-12

Standard Specification for Precipitation Hardened or Cold Worked, Seamless Nickel Alloy Pipe and Tube

ABSTRACT
This specification covers high strength, seamless pipe and tube of nickel alloys (UNS N07022, UNS N07725, and UNS N07740). Pipe and tube shall be supplied in the cold worked or cold worked and precipitations hardened or solution annealed plus precipitation hardened and descaled conditions. When atmosphere control is used, descaling is not necessary. Each pipe or tube shall be tested by the manufacturer by either hydrostatic or a non-destructive electric test in accordance with Specification B829. This specification also describes chemical requirements, heat treatments, and mechanical properties, as well as calculation of mass or weight, sampling of chemical analysis, sampling for mechanical testing, specimen preparation, inspection, and certification. There shall be one test per lot for chemical analysis and one test per lot for tension test. If the specimen used in the mechanical test of any lot fails to meet the specified requirements, tow additional specimens shall be taken from different sample pieces and tested. The results of the tests on both of these specimens shall meet the specified requirements.
SCOPE
1.1 This specification covers high strength, seamless pipe and tube of nickel alloys (UNS N07022, UNS N07725, and UNS N07740) as shown in Table 1.
1.2 Pipe and tube shall be supplied in the cold worked or cold worked and precipitations hardened or solution annealed plus precipitation hardened and descaled conditions. When atmosphere control is used, descaling is not necessary.
1.3 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.
1.4 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 and health practices, and determine the applicability of regulatory limitations prior to use.
