ASTM B677-21

Standard Specification for Nickel-Iron-Chromium-Molybdenum and Iron-Nickel-Chromium-Molybdenum-Copper Seamless Pipe and Tube

ABSTRACT
This specification covers UNS N08925, N08354, and N08926 alloy seamless, cold-worked or hot-finished pipes and tubes for use in general corrosive service. The materials should be supplied in solution-treated condition, heat treated and quenched in water or rapidly cooled by other means. The material chemical composition, mechanical properties, and required response to hydrostatic and nondestructive tests should conform to the values contained in this specification and related ASTM standards.
SCOPE
1.1 This specification covers UNS N08925, UNS N08354, and UNS N089262 seamless, cold-worked or hot-finished pipe and tube intended for general corrosive service.  
1.2 ASTM International has adopted definitions whereby some grades, such as UNS N08904 previously in this specification, were recognized as stainless steels, because those grades have iron as the largest element by mass percent. Such grades are under the oversight of ASTM Committee A01 and its subcommittees. The products of N08904 previously covered in this specification are now covered by Specifications A269 and A312/A312M.  
1.3 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.  
1.4 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.  
1.5 This 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.
