(Main)Founding - Low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications
Founding - Low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications
This European Standard defines the grades and the corresponding requirements for low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications.
These requirements are specified in terms of
chemical composition: as given for each of the grades,
graphite form and metal structure: spheroidal graphite in a predominantly ferritic matrix,
mechanical properties measured on machined test pieces prepared from cast samples.
This European Standard does not cover technical delivery conditions for iron castings, see EN 1559 1 [1] and EN 1559 3 [2].
Gießereiwesen - Niedriglegiertes ferritisches Gusseisen mit Kugelgraphit für Anwendungen bei höheren Temperaturen
Diese Europäische Norm legt die Sorten und die entsprechenden Anforderungen für niedriglegiertes ferritisches Gusseisen mit Kugelgraphit für die Anwendung bei höheren Temperaturen fest.
Diese Anforderungen sind festgelegt bezüglich der:
- chemischen Zusammensetzung: wie für jede Sorte angegeben;
- Graphitform und Matrixstruktur: Kugelgraphit in einer überwiegend ferritischen Matrix;
- mechanischen Eigenschaften, die an bearbeiteten Proben ermittelt wurden, die aus gegossenen Probestücken entnommen wurden.
Diese Europäische Norm enthält keine Technischen Lieferbedingungen für Gussstücke aus Gusseisen, siehe EN 1559 1 [1] und EN 1559 3 [2].
Fonderie - Fontes ferritiques à graphite sphéroïdal faiblement alliées pour applications à haute température
La présente Norme européenne définit les nuances et les exigences correspondantes relatives aux fontes
ferritiques à graphite sphéroïdal faiblement alliées, pour applications à haute température.
Ces exigences sont spécifiées en termes de :
⎯ composition chimique : telle que donnée pour chaque nuance,
⎯ forme du graphite et structure de la matrice : graphite sphéroïdal dans une matrice à prédominance
ferritique,
⎯ propriétés mécaniques mesurées sur des éprouvettes usinées, préparées à partir d’échantillons coulés.
La présente Norme européenne ne couvre pas les conditions techniques de fourniture des pièces moulées en
fonte, voir l’EN 1559-1 [1] et l’EN 1559-3 [2].
Livarstvo - Malolegirana nodularna litina za uporabo pri povišanih temperaturah
Ta evropski standard določa razrede in ustrezne zahteve za malolegirane nodularne litine za uporabo pri povišanih temperaturah.
Te zahteve se določijo na podlagi:
– kemijske sestave: kakor je določena za vsak razred;
– oblike grafita in strukture kovine: kroglasti grafit v pretežno feritni matriki;
– mehanskih lastnosti, izmerjenih na strojno obdelanih preskusnih kosih iz litih vzorcev.
Ta standard ne zajema tehničnih dobavnih pogojev za železne odlitke (glejte standarda EN 1559-1 in EN 1559-3).
