1. Scope
1.1 This specification covers general requirements that shall apply to stainless wire and wire rods. Wire rods are a semifinished product intended primarily for the manufacture of wire. Wire is intended primarily for cold forming, including coiling, stranding, weaving, heading and machining as covered under the latest revision of each of the following ASTM specifications: A313/A313M, A368, A478, A492, A493, A580/A580M, and A581/A581M. 1.2 In case of conflicting requirements, the individual ma- terial specification and this general requirement specification shall prevail in the order named. 1.3 General requirements for flat products other than wire are covered in Specification A480/A480M. 1.4 General requirements for bar and billet products are covered in Specification A484/A484M. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.6 Unless the order specifies the applicable metric specifi- cation designation, the material shall be furnished in the inch-pound units. 1.7 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 bar, n—wire that has been straightened and cut (see Specification A484/A484M); however, a straightened and cut small diameter product is often called straightened and cut wire. 3.1.2 wire, n—as covered by this specification and the specifications itemized in 1.1, is any round or shaped cold- reduced product, in coils only, produced by cold-finishing coiled wire rod. 3.1.3 wire rods, n—semifinished product intended primarily for the manufacture of wire; are hot-rolled generally to an approximate round cross section in continuous length coils.
4. Materials and Manufacture
4.1 The material may be furnished in one of the conditions detailed in the applicable material specification, that is, annealed, bright annealed, cold worked, or as otherwise speci- fied on the purchase order. 4.2 A variety of finishes, coatings, and lubricants are avail- able. The particular type used is dependent upon the specific end use. Unless otherwise specified, the finish, coating, and lubricant will be furnished as required by the individual material specification or purchase order.
5. Chemical Composition
5.1 Heat or Cast Analysis—The chemical analysis of each heat shall be determined in accordance with the applicable material specification and Test Methods, Practices, and Termi- nology A751. 5.1.1 The analysis of each heat shall be made from a test sample taken during the pouring of the melt, or from the in-process product later in the manufacturing flow. 5.1.2 The heat analysis shall conform to the chemical requirements for each of the specified elements for the grade ordered, as listed in the applicable product specification. 5.1.3 All commercial metals contain small amounts of elements other than those which are specified. It is neither practical nor necessary to specify limits for unspecified ele- ments that can be present. The producer is permitted to analyze for unspecified elements and is permitted to report such analyses. The presence of an unspecified element and the reporting of an analysis for that element shall not be a basis for rejection unless the presence of that element causes the loss of a property typically expected for that metal for the type and quality ordered. 5.1.4 The purchaser is permitted to require in the purchase order a maximum limit for an individual element not specified in the product specification. Such a requirement for an element not listed in the product specification, when acknowledged in the order acceptance, shall be treated as a specified element, with determination of chemical analysis and reporting of that analysis.
