1、Designation: B673 05 (Reapproved 2011)Standard Specification forUNS N08925, UNS N08354, and UNS N08926 Welded Pipe1This standard is issued under the fixed designation B673; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers UNS N08925, UNS N08354,and UNS N08926* welded pipe for general corrosion applica-tions.1.2
3、 This specification covers pipe sizes in schedules shownin Table 1.1.3 ASTM International has adopted definitions wherebysome grades, such as UNS N08904, previously in this speci-fication were recognized as stainless steels, because thosegrades have iron as the largest element by mass percent. Suchg
4、rades are under the oversight of ASTM Committee A01 andits subcommittees. The products of N08904 previously coveredin this specification are now covered by Specification A312/A312M.1.4 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematic
5、alconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including
6、those identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriatesafety and health practices, and determine the applicability ofregulatory limitations prior to use.2.
