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of an identical text or by endorsement, at the latest by May 2008, and conflicting national standards shall be withdrawn at the latest by May 2008.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. 1 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.
