AASHTO M 204M/M 204 – Standard Specification for Uncoated Stress-Relieved Steel Wire for Prestressed Concrete (ASTM A 421/A 421M-15)
AASHTO M 204M/M 204-19 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 application 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.
