ISO 4954:2021 PDF

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 2°mm to 100°mm (see Annex°A);

°°°°°° case-hardening steels with diameters from 2°mm to 100°mm (see Annex°B);

°°°°°° steels for quenching and tempering, including boron alloyed steels (see Table°C.3), with diameters from 2°mm to 100°mm (see Annex°C);

°°°°°° stainless steels with diameters of 0,8°mm up to 50°mm for austenitic steels, up to 25°mm for ferritic steels and up to 100°mm for martensitic steels (see Annex°D).

This document (except Annex°A) 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.
