(Specification)Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloys (UNS N06625 and UNS N06852) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube
Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloys<brk/> (UNS N06625 and UNS N06852) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube
ABSTRACT
This specification covers UNS N06625 and UNS N06852 nickel-chromium-molybdenum-columbium alloys and UNS N06219 nickel-chromium-molybdenum-silicon alloy in the form of cold-worked seamless pipe and tube. UNS N06625 products are furnished in annealed Grade 1 and solution annealed Grade 2 while UNS N06219 and UNS N06852 are in solution annealed condition only. Chemical testing shall be performed on each type of material and shall conform to the chemical composition limits specified for carbon, manganese, silicon, phosphorus, sulfur, chromium, tantalum, columbium, cobalt, molybdenum, iron, aluminum, titanium, copper, and nickel. The material shall undergo tensile testing and shall conform to the required room temperature tensile properties like tensile strength, yield strength, and elongation depending on the heat treatment used and including small diameter and light-walled tubing. Each pipe or tube shall undergo hydrostatic testing and shall conform to the allowable fiber stress and also be examined with a nondestructive electric test as prescribed.
SCOPE
1.1 This 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.
1.1.1 UNS N06625 products are furnished in two grades of different heat-treated conditions:
1.1.1.1 Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).
1.1.1.2 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 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.
1.3 The 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 and health practices, and determine the applicability of regulatory limitations prior to use.
