14、A Summary of Changes section appears at the end of this standardCopyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United StatesThis international standard was developed in accordance with internationally recognized principles on standardization estab
15、lished in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.16. Materials and Manufacture6.1 The steel shall be made by the open-hearth, basic-oxygen, or electric-fur
16、nace process.6.2 The wire, prior to fabrication, shall be thermally treatedor thermally treated and drawn.6.3 The condition or wire (metallurgical and mechanicalproperties) to be used is at the discretion of the purchaser andis generally dependent on the severity of the component part tobe formed.7.
17、 Chemical Composition7.1 The steel shall conform to the requirements for chemicalcomposition prescribed in Table 2 for the grade ordered.7.2 Achemical composition other than those shown in Table2 may be supplied when agreed upon by the manufacturer andpurchaser.7.3 An analysis of each cast or heat s
18、hall 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 representative upon request.7.4 A product analysis may be made by the purchaser. Thechemical composition thus determined, as
19、to elements requiredor restricted, shall conform to permissible variations forproduct analysis as specified in Table 10 in Specification A510.For referee purposes, Test Methods E30 or Test Methods E350shall be used.8. Metallurgical Structure8.1 Austenitic grain size, when specified, shall be deter-m
20、ined in accordance with the requirements of Test MethodsE112 or some other mutually agreeable method.9. Mechanical Properties9.1 Tensile strength is not normally a requirement. Mini-mum or maximum values for tensile strength may be agreedupon between the purchaser and manufacturer and are depen-dent
21、 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 specified in Table 3. Thewrap test is not applicable to wires over 0.312 in. (8 mm).Since the conventional methods wil
22、l 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 shall betaken for each ten coils or fraction thereof in a lot.9.2.3 Location of TestThe test specimen shall be takenfrom
23、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 DefinitionsA370.10. Dimensions and Tolerances10.1 The diameter of the wire shall not vary from thespecified size by more than the tolerance shown in Table 1.11. Workmanship11.1 T
24、he 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 the fabrication of the parts.TABLE 1 Permissible Variations in Wire DiameterNOTE 1For purposes of determining conforman
