1 Scope
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.
