1. Scope 1.1 This speciﬁcation2 covers nickel-chromium-iron alloys (UNS N06600, N06601, N06603, N06690, N06025, and N06045)* andnickel-chromium-cobalt-molybdenum alloy (UNS N06617) in cold-worked annealed, hot-worked annealed, and hot-ﬁnished seamless pipe and tube intended for general corrosion resistant and heat resistant applications. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 The following safety hazards caveat pertains only to the test methodsportion, Section 12, 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2.
