Stress-Relieved Steel Wire for Prestressed Concrete

Introduction

Standard Name: Stress-Relieved Steel Wire for Prestressed Concrete

Standard Number: AASHTO M 204M/M 204-231, ASTM A421/A421M-21

Scope:

This specification covers two types of stress-relieved, round, high-carbon steel wire used in prestressed linear concrete construction.
Type BA wire is used for applications where cold-end deformation is used for anchoring purposes (Button Anchorage).
Type WA wire is used for applications where 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. This applies only when specified in the purchase order or contract.
This specification is applicable for orders in either SI units (M 204M) or inch-pound units (M 204). SI units and inch-pound units are not necessarily equivalent.
