Standard Specification for Uncoated Stress-Relieved Steel Wire for Prestressed Concrete (ASTM A 421/A 421M-10)
standard by American Association of State and Highway Transportation Officials, 2014



AASHTO M 204M/M 204-14 agrees technically with ASTM A 421/A 421M-10 except for minor differences in wording.

This specification covers two types of uncoated 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).
