Nickel-Chromium-Iron Alloys (UNS N06600, N06601, N06603, N06690, N06025, and N06045)* and Nickel-Chromium-CobaltMolybdenum Alloy (UNS N06617) Seamless Pipe and Tube1
This standard is issued under the fixed designation B 167; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

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.
