This European Standard shall be given the status of a national standard, either by publication of an
20、identical text or by endorsement, at the latest by October 2017, and conflicting national standards shall be withdrawn at the latest by October 2017.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 responsibl
21、e for identifying any or all such patent rights. This document supersedes EN 10222-5:1999. 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
22、 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 wit
23、h 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 provides details about significant technical chang
24、es to EN 10222-5:1999. 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
25、 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 10222-5:2017 (E) DIN EN 10222-5:2017-06 4 1 Scope Thi
26、s European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of stainless steels, including creep resisting steels. Chemical composition and mechanical properties are specified. NOTE Once this standard is published in the EU Official Journal (OJEU) under D
27、irective 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 d
28、ata 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 102221 to EN 102225 is structured so that the data related to different materials is in the part allo
29、cated 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 do
30、cuments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10088-1:2014, Stainl

34、y information Shall be in accordance with EN 10222-1. 5.2 Options A number of options are specified in this European Standard and listed below. Additionally the relevant options of EN 10222-1 apply. If the purchaser does not give any information to implement any of these options at the time of enqui
35、ry and order, the products shall be supplied in accordance with the basic specification (see also EN 10222-1). 1) test temperature for the tensile test at elevated temperature, if applicable (see 6.4.3); 2) test temperature of the impact test at low temperature (see 6.4.4); 3) controlled sulphur con
36、tent (see Table 2, footnote b). 6 Requirements 6.1 Steelmaking process and manufacture of the product Shall be in accordance with EN 10222-1. 6.2 Delivery condition The products shall be delivered in the heat treatment condition specified in Table 1. 6.3 Chemical composition and chemical corrosion p
37、roperties 6.3.1 Cast analysis The chemical composition (cast analysis), determined in accordance with EN 10222-1 shall conform to the requirements of Table 2. 6.3.2 Product analysis The product analysis shall not deviate from the specified cast analysis (see 6.3.1) by more than the values specified
38、in Table 3. 6.3.3 Resistance to intergranular corrosion The specifications in Table 4 apply in respect to resistance to intergranular corrosion as defined in EN ISO 3651-2, for austenitic and austenitic-ferritic steels. See EN 10222-1:2017, 9.9, Table 1. NOTE 1 EN ISO 3651-2 is not applicable for te
39、sting martensitic steels. NOTE 2 The corrosion resistance of stainless steels is very dependent on the type of environment and can therefore not always be clearly as certained through laboratory tests. It is therefore advisable to draw on the available experience of the use of the steels. EN 10222-5
