Book excerpt: This document specifies the classification and marking, order content, size and shape requirements, technical requirements, test methods, inspection rules, packaging, transportation, storage, marking, quality certificates for the manufacture of cold-drawn non-alloy steel wire for springs. This document applies to cold-drawn non-alloy steel wire for spring (hereinafter referred to as steel wire) of circular cross-section, for the manufacture of mechanical springs for static and dynamic load applications. The standard tensile strength of special-shaped (such as square) spring steel wire can adopt the value, which is corresponding to the specification of the equivalent cross-sectional area, in this document.
