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.1.1 This specification covers general requirements for carbon 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.Note 1—This metric specification is equivalent to Specification A 510, and is compatible in technical content.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This specification deals with the general requirements for alloy steel rods and uncoated coarse round alloy wire in coils that are not required to meet hardenability band limits. Heat and product analyses shall be used to verify that the required percentage of chemical compositions for carbon, manganese, phosphorus, sulfur, vanadium, titanium, nickel, chromium, molybdenum, copper, tungsten, aluminum, and lead are within the specified limit. Required grain sizes shall be determined and specified as annealed, spheroidize annealed, or patented. Tensile strength for annealed alloy rod and wires shall be evaluated using a tensile tests.1.1 This specification covers general requirements for alloy steel rods and uncoated coarse round alloy wire in coils that are not required to meet hardenability band limits.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.Note 1—This specification is the metric counterpart of Specification A752.
