Scope

Main technical content: This document specifies the classification and designations of heat-treated cold heading steel wires, basic requirements, technical requirements, test methods, inspection rules, packaging, marking, and transportation and storage, as well as quality commitments. This document is applicable to high-quality carbon structural steel wires and alloy structural steel wires (hereinafter referred to as steel wires) with a nominal diameter of 1.00 mm to 45.00 mm, used for the manufacture of fasteners such as rivets, bolts, screws, and studs, as well as cold-formed parts. After the fasteners or cold-formed parts are cold forged or cold extruded, they need to undergo surface carburizing, nitriding, and heat treatment such as quenching and tempering.
