Corrosion resistant steel castings

This document applies to corrosion resistant steel castings for general purposes.
This document relates to castings manufactured from martensitic, austenitic, fully austenitic and
austenitic-ferritic steel grades characterized by their chemical composition (see Table 1) and mechanical properties (see Table 2).
ln cases where castings are joined by welding by the founder, this document applies.
ln cases where castings are welded:
- to wrought products (plates, tubes, forgings);
- or by non-founders,
this document does not apply.

Korrosionsbeständiger Stahlguss

Diese Europäische Norm gilt für korrosionsbeständigen Stahlguss für allgemeine Verwendung.
Diese Norm gilt für aus martensitischen, austenitischen, voll austenitischen und ferritisch-austenitischen Stahlsorten hergestellte Gussstücke, die durch ihre chemische Zusammensetzung (siehe Tabelle 1) und ihre mechanischen Eigenschaften (siehe Tabelle 2) gekennzeichnet sind.
In Fällen, in denen Gussstücke vom Gießer zusammengeschweißt werden, gilt diese Europäische Norm.
In Fällen, in denen Gussstücke geschweißt werden:
-   zusammen mit umformbaren Erzeugnissen (Bleche, Rohre, Schmiedestücke);
-   von anderen als Gießern;
gilt diese Europäische Norm nicht.

Aciers moulés résistant à la corrosion

Le présent document s'applique aux pièces moulées en acier résistant à la corrosion, pour usage général.
Le présent document concerne les pièces moulées en acier de nuances martensitiques, austénitiques, entièrement austénitiques et austéno-ferritiques, caractérisées par leur composition chimique (voir Tableau 1) et leurs propriétés mécaniques (voir Tableau 2).
Le présent document s'applique lorsque les pièces moulées sont soudées par le fondeur.
Lorsque des pièces moulées sont soudées :
- à des produits corroyés (tôles, tubes, pièces forgées) ;
- ou par des non-fondeurs,
le présent document ne s'applique pas.

Korozijsko obstojni jekleni ulitki

Ta dokument se uporablja za korozijsko obstojne jeklene ulitke za splošne namene.
Ta dokument se navezuje na ulitke, proizvedene iz martenzitnih, avstenitnih, v celoti avstenitnih in avstenitno-feritnih razredov jekel, katerih značilnosti določajo njihova kemijska sestava (glej preglednico 1) in mehanske lastnosti (glej preglednico 2).
Ta dokument se uporablja v primerih, ko spajanje ulitkov z varjenjem izvaja livar.
Kadar se ulitke vari
– na gnetene zlitine (plošče, cevi, kovane predmete)
– ali ko varjenje izvajajo osebe, ki niso livarji,
se ta dokument ne uporablja.
