1、Designation: A666 15Standard 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 U.S. Department of Defense.1. Scope*1.1 This specifica
3、tion covers austenitic stainless steels in theannealed and normally required cold-worked conditions forvarious structural, pressure vessel, magnetic, cryogenic, andheat-resisting applications. (This revision of SpecificationA666 replaces prior Specifications A412 and A177.)1.2 The application of thi

15、17.3 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 made from one end of each
16、 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 material produced to Table 2
17、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 Definitions A370.Analternative method of determining field strength may be usedbased on the follow

19、under 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 Test:9.2.1 Bend-test speci
20、mens 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 bendfactor times the specified
21、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 pressure.9.2.3 Control
22、led-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.10.
