AS 1472-2003

Specifies requirements for carbon steel spring wire of round cross-section for mechanical springs, supplied in the following forms: hard-drawn, drawn metallic coated, oil-hardened and tempered, or soft-drawn.

This Standard specifies requirements for carbon steel spring wire of round cross-section for mechanical springs, supplied in one of the following conditions: (a) Hard-drawn. (b) Drawn metallic coated, e.g. drawn-galvanized. (c) Oil-hardened and tempered.(d) Soft-drawn. This Standard applies to wire supplied in the form of coils. It does not cover the testing of wire that is supplied in mechanically straightened cut-lengths, or wire that has been straightened by the user. NOTES: 1 Spring wires for bedding and seating applications are covered by AS 2266. 2 In this Standard the term ‘drawing’, alone or in combination, or a variation of ‘drawing’, such as ‘drawn’, is intended to embrace any other technically feasible means, such as ‘rolling’, by which cold-working of steel feedstock enables wire of round cross-section to be achieved. 3 Mechanical straightening introduces small, but significant, changes in diameter and mechanical properties (e.g. tensile strength) of as-drawn spring wire, and the degree of change varies with the straightening technique employed. 4 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A. 5 Alternative means for determining compliance with this Standard are given in Appendix B.
