Heat-treatable steels, alloy steels and free-cutting steels - Part 3: Case-hardening steels (ISO 683-3:2019)
This document specifies the technical delivery requirements for
— semi-finished products, hot formed, e.g. blooms, billets, slabs (see NOTE 1),
— bars (see NOTE 1),
— wire rod,
— finished flat products, and
— hammer or drop forgings (see NOTE 1)
manufactured from the case-hardening non-alloy or alloy steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1 and in one of the surface conditions given in Table 2.
The steels are, in general, intended for the manufacture of case-hardened machine parts.
NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are covered under semi-finished products or bars and not under the term "hammer and drop forgings".
NOTE 2 For International Standards relating to steels complying with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.
In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex A).
In addition to this document, the general technical delivery requirements of ISO 404 are applicable.

Les aciers sont en général destinés à la fabrication de pièces mécaniques cémentées.
NOTE 1 Les produits semi-finis forgés par martelage (blooms, billettes, brames, etc.), les anneaux laminés sans soudure et les barres forgées par martelage figurent parmi les produits semi-finis ou les barres, et non sous l'appellation «pièces forgées par martelage ou estampage».
NOTE 2 Pour les Normes internationales relatives aux aciers qui sont conformes aux exigences de composition chimique du Tableau 3, mais fournis sous d'autres formes de produits ou dans des états de traitement autres que ceux indiqués ci-dessus, ou qui sont destinés à des applications spéciales, ainsi que pour d'autres Normes internationales analogues, voir la Bibliographie.
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 A).
En complément du présent document, les conditions générales techniques de livraison de l'ISO 404 sont applicables.
Toplotno obdelana, legirana in avtomatna jekla - 3. del: Cementacijska jekla (ISO 683-3:2019)
Ta dokument določa tehnične dobavne zahteve za:
– vroče oblikovane polizdelke, npr. bloke, palice, plošče (glej OPOMBO 1),
– palice (glej OPOMBO 1),
– valjane žice,
– končne ploščate izdelke in
– izkovke, kovane s padalnimi kladivi (glej OPOMBO 1),
izdelane iz nelegiranih ali legiranih cementacijskih jekel, navedenih v preglednici 3, ter dobavljenih v enem od
stanj toplotne obdelave, podanih za različne vrste izdelkov v preglednici 1, in enem od
površinskih stanj, podanih v preglednici 2.
Jekla so na splošno namenjena za izdelavo cementiranih strojnih delov.
OPOMBA 1: S kladivom kovani polizdelki (bloki, palice, plošče itd.), nevarjeni valjani obročki in
s kladivom kovani drogovi so v nadaljevanju zajeti pod polizdelki ali drogovi in ne pod izrazom »izkovki, kovani
s padalnimi kladivi«.
OPOMBA 2: Za mednarodne standarde v zvezi z jekli, skladnimi z zahtevami za kemično
sestavo v preglednici 3, ki pa so dobavljena v drugih oblikah izdelkov ali stanjih obdelave, kot so podani zgoraj, ali
namenjena za posebne aplikacije, in za druge povezane mednarodne standarde glejte bibliografijo.
V posebnih primerih so lahko različice teh splošnih tehničnih dobavnih zahtev ali dodatki k njim
predmet sporazuma v času povpraševanja in naročila (glej točko 5.2 in dodatek A).
Poleg tega dokumenta se uporabljajo tudi zahteve splošnih dobavnih pogojev iz standarda ISO 404.
