Bright steel products - Technical delivery conditions - Part 1: General
This part of prEN 10277 specifies the general technical delivery conditions for bright steel bars in the drawn, turned or ground condition, in straight lengths and of the following steel types:
a) steels for general engineering purposes as specified in EN 10277-2;
b) free-cutting steels as specified in EN 10277-3;
c) case hardening steels as specified in prEN 10277-4;
d) steels for quenching and tempering as specified in EN 10277-5.
It does not cover cold rolled products and cut lengths produced from strip or sheet by cutting.
In special cases variations in these technical delivery requirements or additions to them may form the subject of an agreement at the time of enquiry and order (see Annex B).
In addition to the specifications of this European Standard, the general technical delivery requirements of EN 10021 are applicable, unless otherwise specified.

steel products are defined according to their shape and dimensions in EN 10079. In particular the following definitions are reproduced
3.2.1 drawn products (3.4.5.1, EN 10079:2007) products of various cross section shapes obtained, after descaling, by drawing of hot rolled bars or rod on a draw bench (cold deformation without removing material) NOTE
This operation gives the product special features with respect to shape, dimensional accuracy and surface finish. In addition, the process causes cold working of the product, which can be eliminated by subsequent heat treatment. Products in lengths are delivered straightened regardless of size.
3.2.2 turned products (3.4.5.2, EN 10079:2007) round bars produced by turning on a lathe where the product can be further processed by straightening and polishing NOTE 1 This operation gives the bar special features with respect to shape, dimensional accuracy and surface finish. The removal of metal is carried out in such a way that the bright product is generally free from rolling defects and surface decarburization. NOTE 2 For technical reasons some bars ordered as hot rolled products may be delivered roughly turned (peeled), nevertheless such products are treated as hot rolled products and not as bright products.
ruling section for heat treatment of a product is the section for which the mechanical properties have been specified (see Annex A). Whatever the actual shape and dimensions of the cross section of the product, the size of its ruling section is expressed as a diameter. This corresponds to the diameter of an “equivalent round bar” which, at the position of its cross section specified for taking test pieces for mechanical tests, will, when being cooled from the austenitising temperature, show the same cooling rate as the actual ruling section of the product concerned at its position for taking test pieces
