38、y isrequired, the purchaser shall specify the details desired.NOTE 2Because of the discontinuous nature of the processing ofcastings into wrought products, it is not always practical to identifyspecific casting analysis with a specific quantity of finished material.4.2 ManufactureThe product shall b
39、e produced by hotworking, cold working, or both, and finished by such coldworking, annealing or heat treatment and straightening as maybe necessary to meet the properties specified.4.2.1 EdgesThe edge shall be drawn, extruded, or rolled;refer to Edge Contours in Section 6.5. Chemical Composition5.1
40、The material of manufacture shall conform to thecompositional requirements prescribed in the product specifi-cation.5.1.1 When a product (check) sample is analyzed by thepurchaser, the material shall conform to the compositionalrequirements within the permitted analytical variance given inthe produc
