(Main)Case hardening steels - Technical delivery conditions
Case hardening steels - Technical delivery conditions
1.1 This European Standard gives the technical delivery requirements for:
- semi-finished products, hot formed, for example blooms, billets, slabs (see NOTE 2 and NOTE 3),
- bars (see NOTE 2),
- rod,
- wide flats, quarto plates,
- hot-rolled sheet/plate and strip,
- hammer and drop forgings (see NOTE 2),
manufactured from the case hardening non alloyed or alloyed steels (see NOTE 4) listed in Table 3 and sup-plied in one of the heat treatment conditions given for the different types of products in Table 1, lines 2 to 7 and in one of the surface conditions given in Table 2.
The steels are in general intended for the fabrication of case-hardened (see Clause 3) machine parts.
NOTE 1 European Standards relating to steels complying with the requirements for the chemical composition in Ta-ble 3 but which are supplied in other product forms or treatment conditions than given above or are intended for special applications, and European Standards for similar steel grades are listed in the Bibliography.
NOTE 2 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are included under semi-finished products or bars and not under the term "hammer and drop forgings".
NOTE 3 Special agreements shall be made when ordering non-deformed continuously cast semi-finished products.
NOTE 4 In accordance with EN 10020, the steels covered by this European Standard are special steels.
1.2 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 A).
1.3 In addition to the specifications of this European Standard, the general technical delivery requirements of EN 10021 are applicable, unless otherwise specified.
Einsatzstähle - Technische Lieferbedingungen
1.1 Diese Europäische Norm legt die technischen Lieferbedingungen fest für
- Halbzeug, warmgeformt, z. B.: Vorblöcke, Knüppel und Vorbrammen (siehe Anmerkungen 2 und 3),
- Stabstahl (siehe Anmerkung 2),
- Walzdraht,
- Breitflachstahl, Quartobleche,
- Warmgewalztes Blech und Band,
- Freiform- und Gesenkschmiedestücke (siehe Anmerkung 2)
aus den in Tabelle 3 aufgeführten unlegierten und legierten Einsatzstählen (siehe Anmerkung 4), die in einem
der für die verschiedenen Erzeugnisformen in Tabelle 1, Zeilen 2 bis 7, angegebenen Wärmebehandlungszustände
und in einer der in Tabelle 2 angegebenen Oberflächenausführungen geliefert werden.
Die Stähle sind im Allgemeinen zur Herstellung einsatzgehärteter (siehe Abschnitt 3) Maschinenteile vorgesehen.
ANMERKUNG 1 Europäische Normen für Stahlsorten mit gleichen Anforderungen an die chemische Zusammensetzung
wie in Tabelle 3, die jedoch in anderen Erzeugnisformen oder Behandlungszuständen geliefert werden oder für besondere
Anwendungsfälle vorgesehen sind, sowie Europäische Normen für ähnliche Stahlsorten sind in den Literaturhinweisen
zusammengestellt.
ANMERKUNG 2 Freiformgeschmiedetes Halbzeug (Vorblöcke, Knüppel, Vorbrammen usw.), nahtlos gewalzte Ringe
und freiformgeschmiedeter Stabstahl sind im Folgenden unter den Begriffen Halbzeug oder Stabstahl und nicht unter dem
Begriff Freiform- und Gesenkschmiedestücke erfasst.
ANMERKUNG 3 Bei Bestellung von unverformtem stranggegossenem Halbzeug sind besondere Vereinbarungen zu
treffen.
ANMERKUNG 4 Entsprechend EN 10020 handelt es sich bei den in dieser Europäischen Norm enthaltenen Stählen
um Edelstähle.
1.2 In Sonderfällen können bei der Bestellung Abweichungen von oder Zusätze zu diesen technischen Lieferbedingungen
vereinbart werden (siehe Anhang A).
Aciers pour cémentation - Conditions techniques de livraison
1.1 La présente norme européenne expose les conditions techniques de livraison concernant les produits suivants :
- demi-produits transformés à chaud, par exemple : blooms, billettes, brames (voir NOTES 2 et 3) ;
- barres (voir NOTE 2) ;
- fils-machine ;
- larges-plats, plaques quarto ;
- tôles/feuilles et bandes laminées à chaud ;
- pièces forgées par martelage ou estampage (voir NOTE 2) ;
fabriqués en aciers non alliés ou alliés pour cémentation (voir NOTE 4) et énumérés dans le Tableau 3 ; ils sont fournis dans l’un des états de traitement thermique indiqués pour les différents types de produits aux lignes 1 à 7 du Tableau 1 et dans l’un des états de surface mentionnés au Tableau 2.
Les aciers sont en général destinés à la fabrication de pièces mécaniques cémentées (voir article 3 ).
NOTE 1 Les Normes européennes relatives aux aciers qui sont conformes aux prescriptions de composition chimique du Tableau 2 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 les Normes européennes relatives à des nuances d’aciers similaires, sont énumérées dans la bibliographie.
NOTE 2 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 3 La commande de demi-produits brut de coulée continue doit faire l'objet d'un accord particulier.
NOTE 4 Conformément à l'EN 10020, les aciers dont traite la présente norme européenne sont des aciers spéciaux.
1.2 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 Annexe A).
