NEN ISO 4954 : 2018现行

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<br>steels and up to 100 mm for martensitic steels (see Annex D).<br>This document (except Annex A) is applicable to the properties of cold-headed or cold-extruded parts<br>which have been subjected to a subsequent heat treatment. As the properties of the parts in the coldheaded 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.<br>In addition to this document, the general technical delivery requirements of ISO 404 are applicable
