ASTM A555:16 pdf download.Standard Specification for General Requirements for Stainless Steel Wire and Wire Rods.
3.1.1 bar—w ire 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—as covered by this specification and the spedflcations 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—semifinished product intended primarily for the manufacture of wire. They are hot rolled generally to an approximate round cross section in continuous length coils.
4. Materials and Manufacture
4.1 The material may he furnished in one of the conditions detailed in the applicable material specification, that is, annealed, bright annealed, cold worked, or as otherwise specified on the purchase order.
4.2 A variety of finishes, coatings, and lubricants are available. 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 Terminology A75l.
5.1.1 The analysis of each heat shall he 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 elements 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 he treated as a specified element, with determination of chemical analysis and reporting of that analysis.
5.1.5 The purchaser is permitted to make the requirements for any element more stringent, that is, require higher minimums for elements having minimum requirements or ranges with minimum requirements, or requiring lower maximums for elements having specified maximums, or ranges with maximums. The purchaser is not permitted to make chemical requirements less stringent.
