1.1 This European Standard specifies the technical delivery requirements for - semi-finished products, e.g. blooms, billets, slabs; - bars; - rod; - wide flats; - hot- or cold-rolled stirp and sheet/plate; - forgings manufactured from the nitriding steels listed in table 3 and supplied in one of the heat-treatment conditions given for the different types of products in table 1, line 2 to 4 and in one of the surface conditions given in table 2.The steels are, in general, intended for the fabrication of quenched and tempered and generally machined subsequently nitrided parts.NOTE 1 Some grades from EN 10083-1 are also used for nitriding treatment.NOTE 2 Related European Standards are given in annex E.NOTE 3 Hammer-forged semi-finished products (blooms, billets, slabs etc.) and hammer-forged bars are in the following covered under semi-finished products or bars and not under the term "forgings".1.2 In special cases, variations in these technical delivery requirements or additions to them may from the subject of an agreement at the time of enquiry and order (see annex B).1.3 In addition to the specifications of this European Standard, the general technical delivery requirements of EN 10021 are applicable.
