1.1This specification2 covers nickel-chromium-molybdenum-columbium alloys (UNS N06625 and UNS N06852) and nickel-chromium-molybdenum-silicon alloy (UNS N06219)3 in the form of cold-worked seamless pipe and tube. The general requirements for pipe and tube are covered by Specification B829.
1.1.1UNS N06625 products are furnished in two grades of different heat-treated conditions:
1.1.1.1Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).
1.1.1.2Grade 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.
1.1.2Alloys UNS N06219 and UNS N06852 are supplied in the solution annealed condition only.
1.2The 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.
1.3The following precautionary caveat pertains only to the test methods portion, Section 9, 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
