ISO 4954:2024

Description

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 lists the 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, with diameters from 2¬†mm to 100¬†mm (see Annex¬†C).

This document (except Annex A) also applies to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment.

NOTE            Stainless steels for cold heading and cold extruding are covered by ISO 4954-2.
