GB/T 4357-2022 Translated English of Chinese Standard (GB/T4357-2022, GBT 4357-2022): Cold-drawn unalloyed steel wire for springshttps://www.chinesestandard.net, 21 août 2022 - 33 pages 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. This document does not apply to steel wire for the manufacture of springs, which have high fatigue strength (e.g., valve springs). |
