ASTM A666:15 pdf download.Standard Specification for Annealed or Cold-Worked Austenitic Stainless Steel Sheet, Strip, Plate, and Flat Bar.
7.3 Corrosion samples. if required, shall be taken from material after final annealing and descaling and prior to cold
working.
8. Number of Tests
8. 1 For cold-worked product produced in coil form, one tension test shall be made from each end of each coil. One bend test shall be made from one end of each coil.
8.2 For cold-worked flat bar and plate products, two tension test and one bend test shall he niade on each size of flat bar and each thickness of plate from each heat in a lot annealed in a single charge or under the same conditions in a continuous furnace.
8.3 Annealed material produced to Table 2 requirements shall be tested in accordance with Specification A480/A480M.
9.1 .2 The requirement of this specification for yield strength will he considered as having been fulfilled if the extension under load for the specified yield strength does not exceed the specified values. The values obtained in this manner should not, however, be taken as the actual yield strength for 0.2 %. In case of dispute, the offset method of determining yield strength shall be used.
9.2 Bend Test:
9.2.1 Bend-test specimens shall withstand cold bending without cracking when subjected to either the free-bend method or the controlled-bend (V-block) method at the condition specified by Table 3 or Table 4, respectively. Specimens shall he bent around a diameter equal to the product of the bend factor times the specified thickness of the test specimen. The choice of test method for materials in conditions other than annealed shall be at the option of the seller.
9.2.2 Free-bend test specimens shall be bent cold, either by pressure or by blows. However, in the case of dispute, tests shall be made by pressure.
9.2.3 Controlled-bend (V-block) test specimens shall be bent cold by means of V-blocks or a mating punch and die having an included angle of 45° and with proper curvature of surface at the bend areas to impart the desired shape and
diameter of bend to the specimen.
