1、Designation: A403/A403M 12A403/A403M 13Standard 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

2、 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.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers w

3、rought stainless steel fittings for pressure piping applications.21.2 Several grades of austenitic stainless steel alloys are included in this specification Grades are designated with a prefix, WPor CR, based on the applicable ASME or MSS dimensional and rating standards, respectively.1.3 For each o

4、f the WP stainless grades, several classes of fittings are covered, to indicate whether seamless or weldedconstruction was utilized. Class designations are also utilized to indicate the nondestructive test method and extent ofnondestructive examination (NDE). Table 1 is a general summary of the fitt

5、ing classes applicable to all WPgrades of stainless steelcovered by this specification. There are no classes for the CR grades. Specific requirements are covered elsewhere.1.4 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable

6、“M” specification designation (SI units), the material shall be furnished to inch-pound units.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact

7、equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in non-conformance with the standard.1.6 This specification does not apply to cast steel fittings. Austenitic stainless steel castings are covered in SpecificationsA351/A351M
