3、ense.1. Scope*1.1 This specification2covers hot- and cold-finished bars ofstainless steel, including rounds, squares, and hexagons, andhot-rolled or extruded shapes such as angles, tees, and channelsfor use in boiler and pressure vessel construction.2NOTE 1There are standards covering high nickel, c
4、hromium, auste-nitic corrosion, and heat-resisting alloy materials. These standards areunder the jurisdiction of ASTM Subcommittee B02.07 and may be foundin Annual Book of ASTM Standards, Vol 02.04.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.
5、 The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 Unless the order specifies the applicable “M” specifica-tion designation, the materia
6、l shall be furnished to the inch-pound units.2.

United StatesThis international standard was developed in accordan
15、ce with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15. Chemical Composition5.1 Chemical
16、 composition shall be reported to thepurchaser, or his representative, and shall conform to therequirements specified in Table 1.5.2 When a product analysis is performed or requested bythe purchaser, the tolerance limits as described in SpecificationA484/A484M apply unless Supplementary Requirement
17、S3 isinvoked.5.3 Methods and practices relating to chemical analysisrequired by this specification shall be in accordance with TestMethods, Practices, and Terminology A751.6. Grain Size for Austenitic Grades6.1 All austenitic grades shall be tested for average grainsize by Test Methods E112.6.2 The
18、H grades shall conform to an average grain size asfollows:6.2.1 ASTM No. 6 or coarser for Types 304H, 309H, 310H,and 316H,6.2.2 ASTM No. 7 or coarser for Types 321H, 347H, and348H.6.3 For S32615, the grain size as determined in accordancewithTest Methods E112, comparison method, Plate 11, shall beNo
19、. 3 or finer.6.4 For N08810 and N08811, the average grain size asdetermined in accordance with Test Methods E112 shall beNo. 5 or coarser.6.5 Supplementary Requirement S1 shall be invoked whennonH grade austenitic stainless steels are ordered for ASMECode applications for service above 1000F 540C.7.
20、 Mechanical Properties Requirements7.1 The material shall conform to the mechanical propertyrequirements specified in Table 2 for the grade ordered.At leastone room-temperature test shall be performed by the manufac-turer on a sample from at least one bar or shape from each lotof material.7.2 The yi
21、eld strength shall be determined by the offset(0.2 %) method as prescribed in Test Methods and DefinitionsA370.7.3 Martensitic material supplied in the annealed conditionshall be capable of meeting the hardened and temperedmechanical properties when heat treated.7.4 Hardness measurements, when requi
22、red, shall be madeat a location midway between the surface and the center of thecross section.7.5 Martensitic grades shall be capable of meeting thehardness requirements after heat treating as specified in Table3.8. Corrosion Testing8.1 Austenitic stainless steels solution annealed by thealternative
23、 method shall be tested and pass the intergranularcorrosion test requirements described in S2.9. Testing for Intermetallic Compounds9.1 When specified by the purchaser in the purchase order,the manufacturer shall test the austenitic or austenitic-ferritic(duplex) stainless steel material in its fina
24、l condition inaccordance with supplementary test requirements S6.NOTE 2Many, if not all, duplex stainless steels and some austeniticstainless steels will form intermetallic phases or compounds such assigma, chi, and laves phases when exposed to temperatures below thespecified annealing temperature o
25、r cooled slowly from a higher tempera-ture during casting, welding, or annealing. These phases can have anegative effect on mechanical properties and corrosion resistance. Thesephases can typically be removed by correct annealing and coolingpractices. The presence of these phases can be demonstrated
26、 by tests,typically involving metallography, impact toughness, or corrosionresistance, although the testing requirements may be different for differentalloy grades. Such testing may or may not be routinely performed by themanufacturer.10. Certification10.1 The material manufacturers certificate of c
27、ompliancecertifying that the material was manufactured and tested inaccordance with this specification, together with a report of theresults required by this specification and the purchase order,shall be furnished at the time of shipment.
