AASHTO M 204M/M 204

Abstract

This specification covers two types of uncoated stress-relieved, round, high-carbon steel wire commonly used in prestressed linear concrete construction, as follows: <br>Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage), and <br>Type WA wire is used for applications in which the ends are anchored by wedges, and no cold-end deformation of the wire is involved (Wedge Anchorage). <br>Supplement 1 describes low-relaxation wire and relaxation testing for that product. <br>This specification is applicable for orders in either SI units (M 204M) or in inch-pound units (M 204). SI units and inch-pound units are not necessarily equivalent. Inch-pound units are shown in brackets in the text for clarity, but they are the applicable values when the material is ordered to M 204.
