This part specifies the classifications and designations, order contents, dimension, shape, weight and permissible tolerance, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of steel wire for cold heading and cold forging intended for heat treatment.
This part is applicable to the carbon constructional quality steel wires and alloy structure steel wires (hereinafter referred to as steel wire) for making fasteners and cold assemblies such as rivet, bolts, screws and stud bolts. After the fasteners and cold assemblies is finished through cold heading and cold forging, they need to be subjected to heat treatment such as surface carburizing, nitriding and tempering, etc.
