1、Designation: A403/A403M 15Standard Specification forWrought Austenitic Stainless Steel Piping Fittings1This standard is issued under the fixed designation A403/A403M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last

2、 revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers wrought s

3、tainless steel fittingsfor pressure piping applications.21.2 Several grades of austenitic stainless steel alloys areincluded in this specification Grades are designated with aprefix, WP or CR, based on the applicable ASME or MSSdimensional and rating standards, respectively.1.3 For each of the WP st

4、ainless grades, several classes offittings are covered, to indicate whether seamless or weldedconstruction was utilized. Class designations are also utilizedto indicate the nondestructive test method and extent ofnondestructive examination (NDE). Table 1 is a generalsummary of the fitting classes ap

5、plicable to all WP grades ofstainless steel covered by this specification. There are noclasses for the CR grades. Specific requirements are coveredelsewhere.1.4 This specification is expressed in both inch-pound unitsand in SI units. However, unless the order specifies theapplicable “M” specificatio
