1、Designation: A 193/A 193M 09Standard Specification forAlloy-Steel and Stainless Steel Bolting Materials for HighTemperature or High Pressure Service and Other SpecialPurpose Applications1This standard is issued under the fixed designationA 193/A 193M; the number immediately following the designation

2、 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 agenci

3、es of the Department of Defense.1. Scope*1.1 This specification2covers alloy and stainless steel bolt-ing material for pressure vessels, valves, flanges, and fittingsfor high temperature or high pressure service, or other specialpurpose applications. The term bolting material as used in thisspecific

4、ation covers bars, bolts, screws, studs, stud bolts, andwire. Bars and wire shall be hot-wrought. The material may befurther processed by centerless grinding or by cold drawing.Austenitic stainless steel may be carbide solution treated orcarbide solution treated and strain-hardened. When strainharde

5、ned austenitic steel is ordered, the purchaser should takespecial care to ensure that Appendix X1 is thoroughly under-stood.1.2 Several grades are covered, including ferritic steels andaustenitic stainless steels designated B5, B8, and so forth.Selection will depend upon design, service conditions,

6、me-chanical properties, and high temperature characteristics.1.3 The following referenced general requirements are in-dispensable for application of this specification: SpecificationA 962/A 962M.NOTE 1The committee formulating this specification has includedfifteen steel types that have been rather

7、extensively used for the presentpurpose. Other compositions will be considered for inclusion by thecommittee from time to time as the need becomes apparent.NOTE 2For grades of alloy-steel bolting material suitable for use atthe lower range of high temperature applications, reference should bemade to

8、 Specification A 354.NOTE 3For grades of alloy-steel bolting material suitable for use inlow temperature applications, reference should be made to SpecificationA 320/A 320M.1.4 Nuts for use with this bolting material are covered inSection 14.1.5 Supplementary Requirements S1 through S14 are pro-vide

9、d for use when additional tests or inspection are desired.These shall apply only when specified in the purchase order.1.6 This specification is expressed in both inch-pound unitsand in SI units. However, unless the order specifies theapplicable M specification designation (SI units), the materialsha

10、ll be furnished to inch-pound units.1.7 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two system

11、s may result in non-conformancewith the standard. Within the text, the SI units are shown inbrackets.2.
