Heat treatable steels, alloy steels and free-cutting steels - Part 5: Nitriding steels (ISO 683-5:2017)
ISO 683-5:2017 gives the technical delivery requirements for
- semi-finished products, e.g. blooms, billets, slabs (see note 1),
- bars (see note 1),
- wire rod,
- hot-rolled plates (see note 2), and
- hammer or drop forgings (see note 1)
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, rows 2 to 5, and in one of the surface conditions given in Table 2.
The steels are generally intended for the fabrication of quenched and tempered and, subsequently, nitriding machine parts.
The requirements for mechanical properties given in this document are restricted to the sizes given in Table 6.
NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are in the following covered under semi-finished products or bars and not under the term "hammer and drop forgings".
NOTE 2 The term "plate" includes in the following also wide flats unless otherwise stated.
In special cases, variations in these technical delivery requirements or additions to these requirements can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B).
In addition to this document, the general technical delivery requirements of ISO 404 are applicable.

Le présent document fournit les conditions techniques de livraison des
— demi-produits, par exemple blooms, billettes, brames (voir Note 1),
— barres (voir Note 1),
— fil machine,
— tôles laminées à chaud (voir Note 2), et
— pièces forgées par martelage ou estampage (voir Note 1)
fabriqués à partir des aciers pour nitruration énumérés dans le Tableau 3 et livrés dans l’un des états de traitement thermique donnés pour les différents types de produits dans le Tableau 1, aux lignes 2 à 5, et dans l’un des états de surface donnés dans le Tableau 2.
Les aciers sont en général destinés à la fabrication de pièces mécaniques trempées et revenues, puis nitrurées.
Les exigences relatives aux caractéristiques mécaniques données dans le présent document sont limitées aux dimensions données dans le Tableau 6.
NOTE 1 Les demi-produits forgés par martelage (blooms, billettes, brames, etc.), les couronnes laminées sans soudure et les barres forgées par martelage figurent parmi les demi-produits ou les barres, et non sous l’appellation «pièces forgées par martelage et estampage».
NOTE 2 Le terme «tôle» comprend également les larges plats, sauf indication contraire.
Dans certains cas particuliers, il est possible de déroger aux présentes conditions techniques de livraison ou d’en ajouter d’autres, à condition d’en convenir au moment de l’appel d’offres et de la commande (voir 5.2 et Annexe B).
En complément du présent document, les conditions générales techniques de livraison de l’ISO 404 sont applicables.
