EN 10222-1:2017 (E) 4 European foreword This document (EN 10222-1:2017) 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of an identical text or by endorsement, at the latest by October 2017, and conflicting national standards shall be withdrawn at the latest by October 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 10222-1:1998. 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 2014/68/EU. For relationship with EU Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document. EN 10222 consists of the following parts under the general title “Steel forgings for pressure purposes”:
— Part 1: General requirements for open die forgings — Part 2: Ferritic and martensitic steels with specified elevated temperature properties — Part 3: Nickel steels with specified low temperature properties — Part 4: Weldable fine grain steels with high proof strength — Part 5: Martensitic, austenitic and austenitic-ferritic stainless steels. Annex C provide details about significant changes to the versions EN 10222-1:1998. According to the CEN-CENELEC Internal Regulations, the national standards organisations 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, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 10222-1:2017 (E) 5 1 Scope This Part of this European Standard specifies the general technical delivery conditions for open die steel forgings, ring rolled products and forged bars for pressure purposes. NOTE Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222–1 to EN 10222 «5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. General information on technical delivery conditions is given in EN 10021. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The post-weld heat treatment and the mechanical properties to be obtained after testing these samples in accordance with Clause 9 shall be agreed between the purchaser and the manufacturer. NOTE 1 If any additional or unforeseen post-weld heat treatment is applied by the purchaser, the heat treatment temperature cannot exceed the temperature of the final heat treatment, i.e. either tempering or post-weld heat treatment applied to the samples. NOTE 2 If required, the purchaser can be supplied with additional test samples cut from the forging after heat treatment in accordance with 6.3.1 with a view to subjecting these samples to additional heat treatment and subsequent mechanical testing for information purposes. NOTE 3 The samples for simulation of post-weld heat treatment exclude test materials supplied for welding tests and can receive the heat treatments referred to in 6.3.1. 6.4 Chemical composition 6.4.1 Cast analysis 6.4.1.1 The cast analysis reported by the steel producer shall apply and comply with the requirements of the individual parts of the EN 10222 series 6.4.1.2 Elements not listed in the composition tables in the relevant part of the EN 10222 series shall not be intentionally added without the agreement of the purchaser except for finishing the cast. 6.4.1.3 Limits on residual incidental elements other than those specified in the relevant part of the EN 10222 series may be agreed at the time of enquiry and order. 6.4.1.4 If so agreed at the time of enquiry and order, the residual elements specified in the order shall be declared on the manufacturer's certificate. 6.4.1.5 If so agreed at the time of enquiry and order, forgings in accordance with EN 10222-2 and EN 10222-4 shall be supplied with a specific maximum carbon equivalent value. The relevant value is based upon cast analysis. The carbon equivalent value (CEV) shall be calculated using the following formula: MnCr + Mo + VNi + CuCEVC +
