Foreword
This document (EN 10213:2007) 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of an identical text or by endorsement, at the latest by May 2008, and conflicting national standards shall be withdrawn at the latest by May 2008.
This document supersedes EN 10213-1:1995, EN 10213-2:1995, EN 10213-3:1995 and EN 10213-4:1995.
This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
EN 10213, Technical delivery conditions for steel castings for pressure purposes is a revision of the European Standard, EN 10213:1995, in four parts:
Part 1: General
Part 2: Steel grades for use at room temperature and elevated temperatures
Part 3: Steel grades for use at low temperatures
Part 4: Austenitic and austenitic-ferritic steel grades
The revision consists of:
merging of the four previous parts and new arrangement of steel grades in tables;
GP240GR has been deleted;
GX10NiCrSiNb32-20 has been 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.Introduction
This European Standard retains the same format for clauses as EN 1559-2:2000. This European Standard needs to be used in conjunction with EN 1559-2:2000. Where no text is given under a clause heading, the corresponding clause of EN 1559-2:2000 applies.
The structure of this European Standard is as follows:
clauses and subclauses preceded by ■ indicates no additional conditions to EN 1559-2;
subclauses and paragraphs 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.Scope
This European Standard applies to steel castings for pressure containing parts. It includes materials which are used for the manufacture of components, for pressure equipment.
This European Standard relates to castings characterised by their chemical composition (see Table 2) and mechanical properties (see Tables 3 to 6).
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.
NOTE For this harmonised supporting standard for materials, presumption of conformity to the Essential Requirements of the Directive is limited to technical data of the material in the standard and does not presume adequacy of the material to specific equipment. Consequently the technical data stated in the material standard should be assessed against the design requirements of the specific equipment to verify that the Essential Requirements of the Pressure Equipment Directive (PED) are satisfied.

General
Unless otherwise agreed welding is permitted, provided that all welds shall conform to the same criteria for non-destructive testing as the relevant part of the casting. A welding procedure qualification is required (it may include prior agreement for major welds, weld maps...) according to EN ISO 11970.

In addition to EN 1559-2:2000:
chemical composition determined by a cast analysis shall conform with the values given in Table 2;
elements unspecified shall not be intentionally added without agreement of the purchaser other than for the purpose of finishing the heat;
permissible deviations between the specified cast analysis and the check analysis on test blocks are indicated EN 1559-2:2000;
•a maximum carbon equivalent value (CEV) of 0,45 % for the cast analysis may be agreed at the time of enquiry and order for grades GP280GH (1.0625) and G20Mn5 (1.6220). The carbon equivalent value shall be calculated according to the following formula:
C

The mechanical properties at room temperature shall conform to the values given in Table 3.
The mechanical properties at low temperature for impact testing:
shall conform to the values given in Table 4 for ferritic and martensitic grades;
•• may be agreed to the values given in Table 5 for austenitic and austenitic-ferritic grades.
They are verified on test blocks. In all cases the maximum thickness shall be limited to 150 mm.
• In cases where the ruling thickness specified by the purchaser is above the maximum thickness given in Table 3, the mechanical properties shall be agreed.
Proof strength at elevated temperatures shall conform to the values given in Table 6.

In those areas where non-destructive testing has been agreed, the required surface condition shall be ensured by the use of an appropriate process.
References to discontinuities shall be expressed in terms of dimension, quantity and location.
Where minor surface defects do not impair the application or if the surface of the casting corresponds to that of the initial sample, they need not be removed.
NOTE Examples of minor surface defects include small areas of sand or slag, small cold laps, small scabs, small shrink-holes, groups of small pores, residues of the moulding material, uneven areas, flash.
A conforming procedure for unacceptable external and internal discontinuities may be agreed between the purchaser and the manufacturer. In the case of as-cast castings, it is recommended that the purchaser discusses with the manufacturer the choice of any non-destructive testing and criteria to determine the acceptability of a subsequently machined surface. Unless specifically agreed, discontinuities revealed on the machined surface are not to be regarded as a non-conformity.
•• If required, the surface condition including burrs and parting line flash shall be agreed upon.
NOTE Examples of acceptable surfaces include surface comparators or another casting used as a reference comparator etc.
Non destructive testing
In addition to EN 1559-2:2000:
• The castings shall be subjected to non destructive examination under conditions agreed at the time of enquiry and order.
every order shall include information about:
non destructive method involved (visual, magnetic particle, liquid penetrant, ultrasonic, radiographic ...);
severity levels for every method;
areas of the casting to be tested (location and extent);
percentage of castings to be inspected.
However, different acceptance criteria can be specified for different areas of the same casting (e.g. inner and outer zones). Moreover for the same area of the casting different acceptance criteria can be specified according to the non destructive methods selected.
The inspection shall be performed according to the relevant European Standard according to Table 1:
