AASHTO M204 – Standard Specification for Stress-Relieved Steel Wire for Prestressed Concrete
This specification covers two types of stress-relieved, round, high-carbon steel wire commonly used in prestressed linear concrete construction:
- Type BA wire is used for applications in which cold-end deformation is used for anchoring purposes (Button Anchorage)
- 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).
