1.1 This specification covers uncoated, high-strength, hard-drawn steel wire for use in the manufacture of prestressed concrete tanks and similar structures. In application, the wire is continuously wrapped on the structure maintaining tension by a device employing a wire drawing die, or mechanical tensioning system without redrawing.

1.2 This specification is applicable only to the condition of the wire as delivered to the user. It is not applicable to the properties or condition of the wire after application.

1.2.1 Type A wire is to be tensioned by drawing through a wire drawing die or by a mechanical system without redrawing.

1.2.2 Type B wire is drawn to finished size by the manufacturer for tensioning by a mechanical system without redrawing.

Note 1-Type A wire when tensioned by drawing through a die, may not function properly if the user does not ensure that during application the surface of the wire is free of rust and foreign materials that can be detrimental to good wire drawing practice. Further, the user should ensure that proper wire drawing techniques are followed, including adequate lubrication, cooling, and proper die mechanics.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
