scope:

This International Standard applies to wrought unalloyed and alloyed steels which are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. lt contains five sections covering the following topics:

Section 1 - general requirements common to all sections.

Section 2 - steels not intended for heat treatment, with diameters from 2 mm to 100 mm.

Section 3 - case-hardening steels with diameters from 2 mm to 100 mm.

Section 4 - steels for quenching and tempering including boron treated steels, with diameters from 2 mm to 100 mm.

Section 5 - stainless steels with diameters of 2 mm up to 25 mm for ferritic, up to 100 mm for martensitic, and up to 50 mm for austenitic steels.

International Standard (except section 2) is not applicable to the properties of cold-headed or cold-extruded park which have not been subjected to a subsequent heat treatment. As the properties of the park in the cold headed or cold extruded and subsequently not-heat-treated condition are largely dependent on the applied coldheading or cold-extruding conditions, these should, if necessary, be a matter of agreement between the purchaser and the manufacturer of the parts.

In addition to this International Standard, the general technical delivery requirements of ISO 404 are applicable.
