Introduction of GB/T 1222-2007

This standard specifies the order contents, dimension, shape, weight, allowable variation, technical requirements, test methods, test rules, packing, marking and quality certificate of hot-rolled, forged and cold drawn spring steel. This standard is applicable to the round spring steel with diameter no larger than 100mm, square steel with side length no larger than 100mm (hereinafter referred to as steel bar), flat spring steel with thickness no larger than 40mm and spring steel wire rod with diameter no larger than 25mm [excluding the wire rod for oil hardening-tempering steel spring wire (YB/T 5365)]. According to the consultation by the supplier and the purchaser, steel bar with diameter or side length greater than 100mm, flat steel with thickness 40mm and wire rod with diameter greater than 25mm can also be supplied. The designation and chemical composition specified in this standard are also applicable to ingot steel, steel billet and their products.
