Name:

Seamless Pipe and Tube as standard B677 Grade UNS N08626

Type Of Tubes

SMLS Pipe B677 Grade UNS N08626

Standard Specification for UNS N08925, UNS N08354, and UNS N08926 Seamless Pipe and Tube
This standard is issued under the fixed designation B677; 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 (´) indicates an editorial change since the last revision or reapproval.

Scope

This specification covers UNS N08925, UNS N08354, and UNS N089262 seamless, cold-worked or hot-finished pipe and tube intended for general corrosive service.
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.
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.
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.
