This Standard specifies requirements for steel wire, plain or deformed, suitable for resistance welding, and intended for use as reinforcement for concrete and for manufacture into welded wire fabric in accordance with AS 1304. It specifically excludes hard-drawn high tensile steel wire for prestressed concrete. The following significant changes to the previous edition have been made: a carbon equivalent is now specified, manufacturing tolerances in lengths have been amended to comply with AS 3600, changes to the bend test have been made, process of manufacture has been deleted and a warning, on the need to avoid excessive cold-working when straightening wires, has been added.

This Standard specifies requirements for steel wire, plain or deformed, suitable for resistance welding, and intended for use as reinforcement for concrete and for manufacture into welded wire fabric in accordance with AS 1304. It specifically excludes hard-drawn high tensile steel wire for prestressed concrete, which is dealt with by AS 1310.NOTES:1 For 'Purchasing guidelines', see Appendix A.2 For 'Means for demonstrating compliance with this Standard', see Appendix B.
