Heat resistant steel castings
This European Standard applies to heat resistant steel castings, for general purposes (non pressure) above 600°C. It applies also to heat resistant nickel and cobalt base alloys. This standard relates to castings manufactured from ferritic, austenitic-ferritic, austenitic steels, nickel and cobalt base alloys (characterised by their chemical composition (see table 1) and mechanical properties (see table 2)). In cases where castings are joined by welding by the founder, this European Standard applies.

Diese Europäische Norm gilt für hitzebeständigen Stahlguß für allgemeine Verwendung (kein Druck) oberhalb 600°C. Sie gilt auch für Nickel- und Cobaltbasislegierungen. Diese Norm gilt für aus ferritischen, austenitisch- ferritischen und austenitischen Stählen sowie aus Nickel- und Cobaltbasislegierungen hergestellte Gußstücke (gekennzeichnet durch ihre chemische Zusammensetzung (siehe Tabelle 1) und mechanische Eigenschaften (siehe Tabelle 2). In Fällen, in denen Gußstücke vom Gießer zusammengeschweißt werden, gilt diese Europäische Norm.
Aciers moulés réfractaires
La présente norme européenne s'applique aux aciers moulés réfractaires, destinés à des applications générales (hors service sous pression) au dessus de 600°C. Elle s'applique également aux alliages à base de nickel et de cobalt. La présente norme européenne s'applique aux pièces moulées en aciers ferritiques, austéno-ferritiques et austénitiques, ainsi qu'en alliages à base de nickel et de cobalt (caractérisés par leur composition chimique (voir tableau1) et leurs caractéristiques mécaniques (voir tableau 2).

Foreword
This document (EN 10295:2002) has been prepared by Technical Committee ECISS/TC 31 "Steel castings", the
secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by April 2003 and conflicting national standards shall be withdrawn at the latest by
April 2003.
Annexes A, B, C, and D are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This draft European Standard retains the same format for clauses as EN 1559-1 and EN 1559-2. It should be used
in conjunction with these standards. Where no text is given under a clause heading, the corresponding clause of
EN 1559-1 or EN 1559-2 applies.
The structure of this standard is as follows :
1)
clauses and sub-clauses preceded by indicates no additional conditions to EN 1559-1 or EN 1559-2 ;
sub-clauses marked with one dot “•” indicate that conditions shall be agreed at the time of enquiry and order ;
sub-clauses and paragraphs marked with two dots “••” indicate that conditions may be agreed at the time of
enquiry and order (optional) ;
sub-clauses without dot marking are mandatory.
1) When additional information is given in a clause or sub-clause of this standard (versus the same clause or sub-clause of
EN 1559-1 or EN 1559-2) it is preceded by "In addition to EN 1559:.".
1 Scope
This European Standard is applicable to heat resistant steel castings, for general purposes (not for pressure
applications) above 600 °C. It is also applicable to heat resistant nickel and cobalt base alloys.
This standard relates to castings manufactured from ferritic, austenitic-ferritic, austenitic steels, nickel and cobalt
base alloys (characterised by their chemical composition [see Table 1] and mechanical properties [see Table 2]).
In cases where castings are joined by welding by the founder, this European Standard applies.
In cases where castings are welded :
to wrought products (plates, tubes, forgings.) ;
or by non founders;
this European Standard does not apply.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter.
For dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
EN 1559-1, Founding – Technical conditions of delivery – Part 1 : General.
EN 1559-2, Founding – Technical conditions of delivery – Part 2 : Additional requirements for steel castings.
3 Terms and definitions
For the purposes of this European Standard the terms and definitions given in EN 1559-1:1997 and EN 1559-
2:2000 apply.
4 Information to be supplied by the purchaser
See EN 1559-1 and EN 1559-2.
5 Designations
See EN 1559-1 and EN 1559-2.
6 Manufacture
6.1 Manufacturing process
6.1.1 Melting
In addition to EN 1559-2 :
alternative processes are left to the discretion of the manufacturer.
6.1.2 Heat treatment
Unless otherwise agreed, the type of heat treatment for ferritic grades shall comply with Table 2. Heat treatment is
mandatory where indicated. For non ferritic grades, their mechanical properties values do correspond to the
"as cast" state.
6.2 Welding operations
6.2.1 General
See EN 1559-1 and EN 1559-2.
6.2.2 Production welding
In addition to EN 1559-2 :
•• Unless otherwise agreed welding is permitted. Welding conditions and post weld treatments are listed in
Annex A, for information only. The grades not listed in Table A.1 are weldable without pre-heating and post
treatment in general, but for complex castings and great wall thicknesses a pre-heating and post-stress relief
annealing may be applied due to the low ductility at room temperature of these grades. Procedure is left to the
discretion of the manufacturer.
6.3 Further processing
See EN 1559-1 and EN 1559-2.
7 Requirements
7.1 General
See EN 1559-1 and EN 1559-2.
7.2 Material
7.2.1 Chemical composition
In addition to EN 1559-2 :
the chemical composition determined by a cast analysis shall comply with the values given in Table 1 ;
limit deviations between the specified cast analysis and the check analysis on test blocks are indicated in
EN 1559-2 ;
elements unspecified in Table 1 shall not be intentionally added without agreement of the purchaser other than
for the purpose of finishing the heat. If not otherwise agreed the maximum values as a mass fraction in %
given in Table 3 shall apply.
7.2.2 Mechanical properties
The mechanical properties shall comply with the values given in Table 2. According to the grades they
7.2.2.1
are determined either by hardness testing or by tensile testing, where these values are specified.
The yield strength values at room temperature correspond to 0,2 % proof strength (R ).
p0,2
7.2.2.2 For use at elevated temperatures the values for creep stress are given in Table B.1 :
rupture stress in 100 h and 1 000 h ;
stress corresponding to 1 % elongation in 10 000 h.
These are mean values out of a scatter band of ± 20 %. Table B.1 is for information only.
7.2.3 Other properties
7.2.3.1 High temperature oxidation resistance
The maximum applicable operating temperatures (see Table C.1) are valid for oxidation resistance in clean natural
air. In other atmospheres, these temperatures can differ widely. The definition for these temperatures is done by a
test, where the loss of mass by oxidation is less than 1 gram per square meter and hour, and at a temperature of
50 K higher this loss is not more than 2 gram per square meter and hour. (For austenitic steel a loss of 1 gram per
square meter and hour is equivalent to a loss of 1,1 mm wall thic
