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.

Overview

EN 10283:2019 - Corrosion resistant steel castings (CEN) defines technical delivery conditions for corrosion‑resistant steel castings for general purposes. It covers castings manufactured from martensitic, austenitic, fully austenitic and austenitic‑ferritic (duplex) steel grades and specifies requirements referenced by chemical composition (Table 1) and mechanical properties and heat treatment (Table 2). The standard applies when castings are welded by the founder (the foundry). It does not apply where castings are welded to wrought products (plates, tubes, forgings) or welded by non‑foundry organizations.

Key topics and requirements

• Material grades and composition: Groups and grade designations (martensitic, austenitic, fully austenitic, ferritic‑austenitic) are defined by cast analysis limits in Table 1.
• Mechanical properties & heat treatment: Tensile and impact requirements and heat‑treatment symbols (+Q, +T, +AT) are given in Table 2 for each grade and thickness range.
• Manufacture and melting: Melting and alternative processes left to manufacturer discretion but subject to agreed requirements.
• Welding: The standard applies when production welding is performed by the founder and gives guidance on preheat, interpass and post‑weld heat treatment; Annex A contains welding group information. Note: certain austenitic grades with C > 0.030 % may risk intergranular corrosion if solution annealing is not performed after welding.
• Inspection and testing: Clause structure follows EN 1559‑1/2 and specifies inspection levels, test units, sampling, test procedures, retest and sorting/reprocessing rules.
• Marking, packaging and complaints: Requirements for marking, packaging, surface protection and complaint handling are included.
• Informative guidance: Annex A - welding guidance; Annex B - physical properties.

Applications and users

EN 10283:2019 is intended for any specification, procurement or manufacturing activity involving corrosion‑resistant steel castings for general engineering use. Typical users include:

• Foundries and casting manufacturers specifying corrosion resistant steel castings
• Design and engineering teams selecting materials for components exposed to corrosive service
• Welding engineers and fabrication planners who need guidance on production welding and post‑weld heat treatment
• Quality, inspection and procurement teams creating or verifying technical contracts and delivery conditions

Practical applications include cast components in corrosive environments where standardised material composition, mechanical performance and welding rules are required.

Related standards

• EN 1559‑1:2011 (Founding - Technical conditions of delivery - Part 1: General)
• EN 1559‑2:2014 (Part 2: Additional requirements for steel castings) - EN 10283:2019 is intended to be used in conjunction with these documents.
• EN 10027‑1 (Designation systems for steels)
• EN ISO 3651‑2 (Resistance to intergranular corrosion testing)

Keywords: EN 10283:2019, corrosion resistant steel castings, martensitic, austenitic, duplex, foundry welding, casting inspection, heat treatment, mechanical properties.
