(Specification)Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloys (UNS N06625) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube
Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloys (UNS N06625) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube
SCOPE
1.1 This specification covers nickel-chromium-molybdenum-columbium alloys (UNS N06625 and UNS N06852) and nickel-chromium-molybdenum-silicon alloy (UNS N06219)* in the form of cold-worked seamless pipe and tube. The general requirements for pipe and tube are covered by Specification B 829.
1.1.1 UNS N06625 products are furnished in two grades of different heat-treated conditions:Grade 1 (annealed)
Material is normally employed in service temperatures up to 1100°F (593°C).Grade 2 (solution annealed)
Material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required. Note 1
Hot-working or reannealing may change properties significantly, depending on working history and temperatures.
1.1.2 Alloys UNS N06219 and UNS N06852 are supplied in the solution annealed condition only.
1.2 The following precautionary caveat pertains only to the test methods portion, Section , 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.
