Abstract:
This specification covers two types of uncoated stress-relieved round high-carbon steel wire commonly used in prestressed linear concrete construction. These two types are the type BA used for applications in which cold-end deformation is used for anchoring purposes and type WA wire which is used for application in which the ends are anchored by wedges, no cold-end deformation of the wire is involved. Required tensile strength, yield strength, and elongation shall be evaluated using stress-relaxation test. Heat analysis shall be used to determine the percentage of specified elements especially sulfur and phosphorus to meet the required chemical composition.
