    1. Scope

    1.1 This specification covers cold-finished wire and hot-finished wire rods in coils. Wire rods are a semi-finished product primarily for the manufacture of wire. Wire includes rounds, squares, hexagons, and special shapes in the more commonly used types of stainless free-machining steels designed especially for optimum machinability and for general corrosion and high-temperature service.

    Note 1—For wire other than those of the free-machining types, see Specification A 580/A 580M.

    1.2 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards; within the text and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

    1.3 Unless the order specifies the applicable M specification designation, the material shall be furnished to the inch-pound units.
