3、rtment of Defense.1. Scope*1.1 This specification2 covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, andhot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction.2NOTE 1There are standards coverin
4、g high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under thejurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol 02.04.1.2 The values stated in either SI units or inch-pound units are to be regarded separa
5、tely as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 Unless the order specifies the applicable “M” specification design

Other Requirements4.1 In addition to the requirements of this specification, all requirements of the current edition
16、s of Specification A484/A484Mshall apply. Failure to comply with the general requirements of Specification A484/A484M constitutes nonconformance with thisspecification.5. Chemical Composition5.1 Chemical composition shall be reported to the purchaser, or his representative, and shall conform to the
17、requirementsspecified in Table 1.5.2 When a product analysis is performed or requested by the purchaser, the tolerance limits as described in SpecificationA484/A484M apply unless Supplementary Requirement S3 is invoked.5.3 Methods and practices relating to chemical analysis required by this specific
18、ation shall be in accordance with Test Methods,Practices, and Terminology A751.6. Grain Size for Austenitic Grades6.1 All austenitic grades shall be tested for average grain size by Test Methods E112.6.2 The H grades shall conform to an average grain size as follows:6.2.1 ASTM No. 6 or coarser for T
19、ypes 304H, 309H, 310H, and 316H,6.2.2 ASTM No. 7 or coarser for Types 321H, 347H, and 348H.6.3 For S32615, the grain size as determined in accordance with Test Methods E112, comparison method, Plate 11, shall be No.3 or finer.6.4 For N08810 and N08811, the average grain size as determined in accorda
20、nce with Test Methods E112 shall be No. 5 No. 5or coarser.6.5 Supplementary Requirement S1 shall be invoked when nonH grade austenitic stainless steels are ordered for ASME Codeapplications for service above 1000F 540C.7. Mechanical Properties Requirements7.1 The material shall conform to the mechan
21、ical property requirements specified in Table 2 for the grade ordered. At least oneroom-temperature test shall be performed by the manufacturer on a sample from at least one bar or shape from each lot of material.7.2 The yield strength shall be determined by the offset (0.2 %) method as prescribed i
22、n Test Methods and Definitions A370.7.3 Martensitic material supplied in the annealed condition shall be capable of meeting the hardened and tempered mechanicalproperties when heat treated.7.4 Hardness measurements, when required, shall be made at a location midway between the surface and the center
23、 of the crosssection.7.5 Martensitic grades shall be capable of meeting the hardness requirements after heat treating as specified in Table 3.8. Corrosion Testing8.1 Austenitic stainless steels solution annealed by the alternative method shall be tested and pass the intergranular corrosiontest requi
24、rements 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 final condition in accordance with supplementary test requirements S6.NOT
25、E 2Many, if not all, duplex stainless steels and some austenitic stainless steels will form intermetallic phases or compounds such as sigma, chi,and laves phases when exposed to temperatures below the specified annealing temperature or cooled slowly from a higher temperature during casting,welding,
26、or annealing. These phases can have a negative effect on mechanical properties and corrosion resistance. These phases can typically be removedby correct annealing and cooling practices. The presence of these phases can be demonstrated by tests, typically involving metallography, impactA479/A479M 152
