15、at the discretion of the purchaser andis generally dependent on the severity of the component part tobe formed.7. Chemical Composition7.1 The steel shall conform to the requirements for chemicalcomposition prescribed in Table 2 for the grade ordered.7.2 A chemical composition other than those shown
16、in Table2 may be supplied when agreed upon by the manufacturer andpurchaser.7.3 An analysis of each cast or heat shall be made by themanufacturer to determine the percentage of elements specifiedin Table 2. The chemical composition thus determined shall bereported to the purchaser or his representat
17、ive upon request.7.4 A product analysis may be made by the purchaser. Thechemical composition thus determined, as to elements requiredor restricted, shall conform to permissible variations forproduct analysis as specified in Table 10 in SpecificationA 510. For referee purposes, Test Methods E 30 or
18、TestMethods E 350 shall be used.8. Metallurgical Structure8.1 Austenitic grain size, when specified, shall be deter-mined in accordance with the requirements of Test MethodsE 112 or some other mutually agreeable method.9. Mechanical Properties9.1 Tensile strength is not normally a requirement. Mini-
19、mum or maximum values for tensile strength may be agreedupon between the purchaser and manufacturer and are depen-dent on the chemical composition, thermal treatment, anddiameter of wire specified.9.2 Wrap Test:9.2.1 RequirementsWire shall wind without fracture on acylindrical mandrel of a diameter
20、specified in Table 3. Thewrap test is not applicable to wires over 0.312 in. (8 mm).Since the conventional methods will not accommodate wiresizes over 0.312 in., an alternative test procedure may beagreed upon between the purchaser and manufacturer.9.2.2 Number of TestsAt least one test specimen sha
21、ll betaken for each ten coils or fraction thereof in a lot.9.2.3 Location of TestThe test specimen shall be takenfrom either end of the coil.9.2.4 Test MethodThe wrap test shall be made in accor-dance with Supplement IV of Test Methods and DefinitionsA 370.10. Dimensions and Tolerances10.1 The diame
22、ter of the wire shall not vary from thespecified size by more than the tolerance shown in Table 1.11. Workmanship11.1 The surface of the wire as received shall be substan-tially free of rust and such other surface imperfections of anature or degree, for the grade ordered, that will be detrimentalto
23、the fabrication of the parts.11.2 Wire drawn as a final operation shall not be kinked orimproperly cast. To test for a cast, a single convolution, or ring,of wire shall be cut from the bundle and placed on a flatsurface. The wire shall lie substantially flat and not spring up.The wire shall not show
24、 a wavy condition.11.3 Each coil of wire shall be one continuous length.11.4 Wire may be processed with welds made prior to wiredrawing. Weld areas need not meet the mechanical require-ments of the specification. If unmarked welds are unacceptableto the purchaser, special arrangements should be made
25、 with themanufacturer at the time of purchase.12. Inspection12.1 The manufacturer shall afford the inspector represent-ing the purchaser all reasonable facilities to satisfy him that theTABLE 1 Permissible Variations in Wire DiameterNOTEFor purposes of determining conformance with this specifica-tio
