Specifies requirements for hard-drawn high-tensile steel wire intended for use in the prestressing of concrete. It provides for wire types in the as-drawn and stress-relieved conditions.

This Standard specifies the requirements for hard-drawn, high-tensile steel wire intended for the prestressing of concrete.The Standard provides for the following wire types:(a) As-drawn condition - round wire only.(b) Stress-relieved condition - either round wire or round wire deformed by indenting or crimping,and stress-relieved to achieve either normal relaxation or low relaxation, as desired.NOTE: Guidelines to purchasers on requirements that should be specified by the purchaser and those that should be agreed at the time of enquiry or order are given in Appendix A.
