Foreword

This document (EN 10293:2015) has been prepared by Technical Committee ECISS/TC 111 “Steel castings and
forgings”, 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by endorsement, at the latest by July 2015 and conflicting national standards shall be withdrawn at the latest by
July 2015.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 10293:2005.

In comparison with EN 10293:2005, the following significant technical changes were made:

— Alignment with the structure of EN 1559-1:2011, "Founding - Technical conditions of delivery - Part 1: General"
and EN 1559-2:2014 "Founding - Technical conditions of delivery - Part 2: Additional requirements for steel
castings";

— New grades (GE270, GE320 and GE360) added.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,

Introduction

This document retains the same format for clauses as EN 1559-1:2011 and EN 1559-2:2014. It should be used in
conjunction with these standards. Where no text is given under a paragraph heading, the corresponding paragraph
of EN 1559-1:2011 and EN 1559-2:2014 applies.

The structure of this document is as follows:

1) 1)
— clauses and subclauses preceded by ■ indicates no additional conditions to EN 1559-1 and EN 1559-2 ;

— clauses and subclauses marked with a single dot • indicate that the conditions shall be agreed at the time of
enquiry and order;

— subclauses marked with two dots •• indicate that conditions may be agreed at the time of enquiry and order
(optional);

— subclauses without dot marking are mandatory.

1 Scope

This European Standard applies to steel castings:

— for general engineering uses. Its uses include machinery (mechanical, electrical...), automotive industries,
railroad, armament, agricultural equipment, mining, etc.

In cases where castings are joined by welding by the founder, this document applies.

In cases where castings are welded:

— to wrought products (plates, tubes, forgings...), or

— by non-founders,

this document does not apply.

In addition to EN 1559-2:2014:

7.2.2.1 The mechanical properties shall conform to the values given in Table 3.

These values apply up to the maximum wall thickness given in Table 3. They are verified on test blocks of relevant
thickness (see 8.4.1 of EN 1559-2:2014). In all cases, the maximum wall thickness of test blocks shall be limited to
150 mm.

• In cases where the ruling thickness defined by the purchaser is above the maximum thickness given in Table 3,
the foreseeable lowering of the mechanical properties shall be agreed.

7.2.2.2 The yield strength values at room temperature correspond to 0,2 % proof strength (Rp0,2).

•• 7.2.2.3 In cases where two impact values are given, at test temperature specified in Table 3 the purchaser
shall state which impact value is required. If there is no such statement in the enquiry and order the impact test
shall be conducted at room temperature.
