scope:

This document specifies technical delivery requirements for the surface quality of round bars, squares, hexagons and wire rod in the hot rolled condition with nominal dimensions dN from 5 mm to 200 mm. This document is applicable to bright products and tool steels, if agreed at the time of enquiry and order between manufacturer and purchaser.

By agreement between manufacturer and purchaser, this document can also be applied to other special profiles.

This document is particularly applicable to steels for engineering and structural applications.

This document does not include any requirements for the permissible depth of surface decarburization.

NOTE The determination of depth of surface decarburization is presented in ISO 3887.

The material standards for steel bars and wire rod can exclude the application of one or other of the surface quality classes of this document. They can also cover requirements for surface quality which deviate from this document. In these cases the requirements of the material standard prevail.
