1、Designation: A193/A193M 15A193/A193M 15aStandard Specification forAlloy-Steel and Stainless Steel Bolting for High Temperatureor High Pressure Service and Other Special PurposeApplications1This standard is issued under the fixed designation A193/A193M; the number immediately following the designatio
2、n indicates the yearof 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.This standard has been approved for use by agenc
3、ies of the U.S. Department of Defense.1. Scope*1.1 This specification2 covers alloy and stainless steel bolting materials and bolting components for pressure vessels, valves,flanges, and fittings for high temperature or high pressure service, or other special purpose applications. See SpecificationA
4、962/A962M for the definition of bolting. Bars and wire shall be hot-wrought and may be further processed by centerless grindingor by cold drawing.Austenitic stainless steel may be carbide solution treated or carbide solution treated and strain-hardened. Whenstrain hardened austenitic stainless steel
5、 is ordered, the purchaser should take special care to ensure that Appendix X1 is thoroughlyunderstood.1.2 Several grades are covered, including ferritic steels and austenitic stainless steels designated B5, B8, and so forth. Selectionwill depend upon design, service conditions, mechanical propertie
6、s, and high temperature characteristics.1.3 The following referenced general requirements are indispensable for application of this specification: SpecificationA962/A962M.NOTE 1The committee formulating this specification has included several steel types that have been rather extensively used for th
7、e present purpose.Other compositions will be considered for inclusion by the committee from time to time as the need becomes apparent.NOTE 2For grades of alloy-steel bolting suitable for use at the lower range of high temperature applications, reference should be made to SpecificationA354.NOTE 3For
8、grades of alloy-steel bolting suitable for use in low temperature applications, reference should be made to Specification A320/A320M.1.4 Nuts for use with bolting are covered in Section 13.1.5 Supplementary Requirements are provided for use at the option of the purchaser. The supplementary requireme
9、nts shallapply only when specified in the purchase order or contract.1.6 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units), the inch-pound units shall apply.1.7 The v
10、alues 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 equivalents; therefore, each system shall be usedindependently of the other. Combining values from the
11、two systems may result in non-conformance with the standard.2.
