27、n The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of patents concerning eight steel grades given in Clause 12, Annex A, Annex B, Annex C and Annex E. CEN takes no position concerning the evidence,
28、validity and scope of this patent right. The holder of this patent right has assured CEN that he/she is willing to negotiate licences either free of charge or under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the hold
29、er of this patent right is registered with CEN. Information may be obtained from: Outokumpu Oyj FI-02200 Espoo, Finland for steel grades 1.4420, 1.4622, 1.4162 (but also consider footnote c in Table 4) and1.4662 Industeel F-71200 Creusot, 56 Rue Clemenceau, France for steel grade 1.4062 Acciai Speci

I-05100 Terni, Italy for steel grades 1.4646, 1.4611 and 1.4613 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above. CEN shall not be held responsible for identifying any or all such p
31、atent rights. CEN and CENELEC maintain online lists of patents relevant to their standards. Users are encouraged to consult the lists for the most up to date information concerning patents (ftp:/ftp.cencenelec.eu/EN/IPR/Patents/IPRdeclaration.pdf).

32、e This European Standard specifies requirements for flat products for pressure purposes made of stainless steels, including austenitic creep resisting steels, in thicknesses as indicated in Tables 7 to 10. The requirements of EN 10028-1 also apply. NOTE 1 The steel grades covered by this European St
33、andard have been selected from EN 100881. NOTE 2 Once this European Standard is published in the Official Journal of the European Union (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 mat
34、erials in this European Standard (Part 1 and Part 7) 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 th
35、e ESRs of the Pressure Equipment Directive are satisfied, needs to be done. 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 cited applies. For undated re
36、ferences, the latest edition of the referenced document (including any amendments) applies.

If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification (see EN 1
42、0028-1). 7.3 Example for ordering 10 plates made of a steel grade with the name X5CrNi18-10 and the number 1.4301 as specified in EN 10028-7 with nominal dimensions, thickness = 8 mm, width = 2 000 mm, length = 5 000 mm; tolerances on dimensions, shape and mass as specified in EN ISO 18286 with thic

45、nt conditions given in Tables 7 to 10. Guidelines for further treatment including heat treatment are given in Annex A. 8.3 Chemical composition and chemical corrosion properties 8.3.1 The chemical composition requirements given in Tables 1 to 4 shall apply in respect of the chemical composition acco
46、rding to the cast analysis. 8.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Tables 1 to 4 by the values listed in Table 5. EN 10028-7:2016 (E) DIN EN 10028-7:2016-10 8 8.3.3 The specifications in Tables 7, 9 and 10 shall apply in respect to resistance t
47、o intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic steels. NOTE 1 EN ISO 3651-2 is not applicable for testing martensitic steels. NOTE 2 The corrosion resistance of stainless steels is very dependent on the type of environment and can therefore no
48、t always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available experience of the use of the steels. 8.4 Mechanical properties 8.4.1 The tensile properties at room temperature and the impact energy at 20 C and at low temperatures as specified in Tables 7
49、to 10 apply for the relevant specified heat treatment condition. NOTE Austenitic stainless steels are insensitive to brittle fracture in the solution annealed condition. As they have a good resistance to shock loads, due to their high impact energy, also at very low (cryogenic) temperatures, they are useful for applications at such temperatures (see also the NOTE to Tables 9 and 10). 8.4.2 The values in Tables 11 to 14 apply for the 0,2 %
