Standard Specification for General Requirements for Wire Rods and Coarse Round Wire, Carbon Steel, and Alloy Steel

ABSTRACT
This specification covers the general requirements for carbon steel wire rods and uncoated coarse round wire in coils or straightened and cut lengths. Chemical compositions are specified by ranges or limits for carbon and other elements. The grades commonly specified for carbon steel wire rods and coarse round wire are presented. Grain size, when specified, and the mechanical properties enumerated in individual specifications shall be determined in accordance with reference test materials.
SCOPE
1.1 This specification covers general requirements for carbon and alloy steel wire rods and uncoated coarse round wire in coils or straightened and cut lengths.  
1.2 In case of conflict, the requirements in the purchase order, on the drawing, in the individual specification, and in this general specification shall prevail in the sequence named.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, inch-pound units are shown in brackets.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1.1 coarse round wire, n—from 0.90 to 25 mm [0.035 to 0.999 in.] in diameter, inclusive, wire that is produced from hot-rolled
wire rods or hot-rolled coiled bars by one or more cold reductions primarily for the purpose of obtaining a desired size with

wire mill practices, including thermal treatment, a wide diversity of mechanical properties and finishes are made available.
3.1.1.1 Discussion—
Coarse round wire is designated by Steel Wire Gauge numbers, common fractions, or decimal parts of an inch, or metric
equivalents. The Steel Wire Gauge system is shown in Table 1. Since the many gauge systems in use may cause confusion, the
purchaser is encouraged to specify wire diameters in inches, decimal parts, or metric equivalents.
3.1.2 straightened and cut wire, n—wire that is produced from coils of wire by means of special machinery which straightens the
wire and cuts it to a specified length.
