Chemical Composition7.1 The material shall conform to the composition limitsspecified in Table 1.
17、7.1.1 A chemical analysis shall be made on each lot ofmaterial as described in Specification B829.7.2 If a product (check) analysis is performed by thepurchaser, the material shall conform to the product analysisvariations prescribed in Specification B829.8. Mechanical and Other Properties8.1 The ma
18、terial shall conform to the mechanical propertieslisted in Table 2.8.1.1 One tension test shall be made on each lot of material.8.2 Grain SizeAnnealed alloy UNS N08332 shall con-form to an average grain size of ASTM No. 5 or coarser. Onetest per lot is required.8.3 Flattening TestOne section of pipe
19、 or tube per lot, notless than 212 in. (63.5 mm) in length, shall be flattened coldbetween parallel plates in two steps. During the first step,which is test for ductility, no cracks or breaks on the inside,outside or end surfaces shall occur until the distance betweenthe plates is less than the valu
20、e H calculates as follows:H 5 1.09 t/0.091t/D! (1)where:H = distance between parallel plates, in.,t = specified wall thickness, in., andD = nominal outside diameter, in.During the second step, which is a test for soundness, theflattening shall be continued until the specimen breaks or theopposite wa
