The ISO 16120 series is applicable to wire rod of non-alloy steel intended for wire drawing and\/or cold rolling. The cross-section can be circular, oval, square, rectangular, hexagonal, octagonal, half-round or another shape, generally with at least 5 mm nominal dimension, and with a smooth surface.<\/p>\n
This document specifies general requirements for non-alloy steel wire rod for conversion to wire. It is not applicable to products for which standards exist or are in development, for example:<\/p>\n
steel wire rod intended for heat treatment;<\/p>\n<\/li>\n
free-cutting steel wire rod;<\/p>\n<\/li>\n
steel wire rod for cold heading and cold extrusion;<\/p>\n<\/li>\n
steel wire rod intended for the production of electrodes and products for welding;<\/p>\n<\/li>\n
steel wire rod for welded fabric for reinforcement for concrete;<\/p>\n<\/li>\n
steel wire rod for ball and roller bearings (see ISO 683\u201117);<\/p>\n<\/li>\n
steel wire rod for wire for high fatigue strength mechanical springs, such as valve springs.<\/p>\n<\/li>\n<\/ul>\n
In addition to the requirements of this document, the general technical delivery requirements specified in ISO 404 apply.<\/p>\n
