BS ISO 4954:2021

This document specifies requirements for non-alloy and alloy steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It also contains specific requirements for: steels not intended for heat treatment, with diameters from 2mm to 100mm (see AnnexA); case-hardening steels with diameters from 2mm to 100mm (see AnnexB); steels for quenching and tempering, including boron alloyed steels (see TableC.3), with diameters from 2mm to 100mm (see AnnexC); stainless steels with diameters of 0,8mm up to 50mm for austenitic steels, up to 25mm for ferritic steels and up to 100mm for martensitic steels (see AnnexD). This document (except AnnexA) is applicable to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. As the properties of the parts in the cold-headed or cold-extruded, and subsequently not-heat-treated condition, are largely dependent on the applied cold-heading or cold-extruding conditions, these are, if necessary, subject to agreement between the purchaser and the manufacturer of the parts.
