This document has been prepared under a mandate given to CEN by the European Commission and the European
22、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 p
23、urposes”: 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, austeni
24、tic and austenitic-ferritic stainless steels. Annex B provides details about significant technical changes to EN 10222-2:1999.

EN 10222-2:2017 (E) DIN EN 10222-2:2017-06 4 1 Scope This part of this European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of ferritic and martensitic steels with specified elevated temperature propert
27、ies. Chemical composition and mechanical properties are specified. 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 material
28、s 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
29、 satisfied, needs to be done. The series EN 102221 to EN 102225 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
30、the data in part 2, 3, 4 or 5. General information on technical delivery condition 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. For dated references, only the edition
31、cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
