AASHTO M 204M/M 204
AASHTO M 204M/M 204 2019 Edition, 2019 Standard Specification for Stress-Relieved Steel Wire for Prestressed ConcreteMore info
Description / Abstract:
This specification covers two types of stress-relieved, round, high-carbon steel wire commonly used in prestressed linear concrete construction, as follows:
Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage), and
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).
A supplementary requirement is provided for use where low-relaxation wire and relaxation testing for that product is required by the purchaser. The supplementary requirement applies only when specified in the purchase order.
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.
