1、Designation: A666 10Standard Specification forAnnealed or Cold-Worked Austenitic Stainless Steel Sheet,Strip, Plate, and Flat Bar1This standard is issued under the fixed designation A666; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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
3、covers austenitic stainless steels in theannealed and normally required cold-worked conditions forvarious structural, architectural, pressure vessel, magnetic,cryogenic, and heat-resisting applications. (This revision ofSpecification A666 replaces prior Specifications A412 andA177.)1.2 The applicati
4、on of this specification, or the use ofmaterial covered by this specification does not automaticallyallow usage in pressure vessel applications. Only annealedconditions of grades specifically approved by the ASME codeare permitted for pressure vessel use.1.3 The values stated in inch-pound units are
5、 to be regardedas the standard. The values given in parentheses are forinformation only.2.

Sampling7.1 Tension and bend-test specimens of sheet, strip, andplate products shall be selected from finished material a
14、nd shallbe selected in the transverse direction, except in the case ofstrip under 9 in. (229 mm) in width, in which case tension testspecimens shall be selected in the longitudinal direction.7.2 Flat bar tension and bend-test specimens shall be se-lected from the finished material and shall be in th
15、e longitudi-nal direction.7.3 Corrosion samples, if required, shall be taken frommaterial after final annealing and descaling and prior to coldworking.8. Number of Tests8.1 For cold-worked product produced in coil form, onetension test shall be made from each end of each coil. One bendtest shall be
16、made from one end of each coil.8.2 For cold-worked flat bar and plate products, two tensiontest and one bend test shall be made on each size of flat bar andeach thickness of plate from each heat in a lot annealed in asingle charge or under the same conditions in a continuousfurnace.8.3 Annealed mate
17、rial produced to Table 2 requirementsshall be tested in accordance with Specification A480/A480M.9. Test Methods9.1 Tension Test:9.1.1 The yield strength shall be determined by the offsetmethod as described in Test Methods and DefinitionsA370.Analternative method of determining field strength may be
18、 usedbased on the following total extension under load:Yield Strength, min. psi Total Extension under Load in 2 in.Gage Length, incl.45 000 0.007175 000 0.0098110 000 0.0125135 000 0.0144140 000 0.01489.1.2 The requirement of this specification for yield strengthwill be considered as having been ful
19、filled if the extensionunder load for the specified yield strength does not exceed thespecified values. The values obtained in this manner shouldnot, however, be taken as the actual yield strength for 0.2 %. Incase of dispute, the offset method of determining yield strengthshall be used.9.2 Bend Tes
20、t:9.2.1 Bend-test specimens shall withstand cold bendingwithout cracking when subjected to either the free-bendmethod or the controlled-bend (V-block) method at the condi-tion specified by Table 3 or Table 4, respectively. Specimensshall be bent around a diameter equal to the product of the bendfact
21、or times the specified thickness of the test specimen. Thechoice of test method for materials in conditions other thanannealed shall be at the option of the seller.9.2.2 Free-bend test specimens shall be bent cold, either bypressure or by blows. However, in the case of dispute, testsshall be made by
22、 pressure.9.2.3 Controlled-bend (V-block) test specimens shall bebent cold by means of V-blocks or a mating punch and diehaving an included angle of 45 and with proper curvature ofsurface at the bend areas to impart the desired shape anddiameter of bend to the specimen.TABLE 1 Chemical Composition R
