21、7:2000 Foreword This European Standard has been prepared by Technical Committee ECISS/TC 22, Steels for pressure purposes - Qualities, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by en
22、dorsement, at the latest by July 2000, and conflicting national standards shall be withdrawn at the latest by July 2000. The steel grades covered by this European Standard have been selected from EN 10088-1, additionally considering austenitic creep resisting steels. Annex H contains national A-devi
23、ations specifying restrictions for the application of this European Standard in Sweden. This European Standard 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 w
24、ith EU Directive(s), see informative annex ZA, which is an integral part of this standard. The other parts of this European Standard are: Part 1 General requirements; Part 2 Non-alloy and alloy steels with specified elevated temperature properties; Part 3 Weldable fine grain steels, normalized; Part
25、 4 Nickel alloy steels with specified low temperature properties; Part 5 Weldable fine grain steels, thermomechanically rolled; Part 6 Weldable fine grain steels, quenched and tempered. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
26、 are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 1 Scope This EN 10028-7 specifies requirements for flat
27、products for pressure purposes made of stainless steels, including austenitic creep resisting steels, in thicknesses as indicated in Tables 6 to 9. The requirements of EN 10028-1 also apply.

Additionally the relevant options of EN
34、 10028-1 apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the supplier shall supply in accordance with the basic specification (see EN 10028-1). a) mechanical properties for increased product thicknesses (see Table 7, footnote 5); b
35、) higher Rp0,2 and Rp1,0 values for continuously hot rolled products (see Table 9, footnote 4 and Table 10, footnote 2); 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, widt
36、h = 2 000 mm, length = 5 000 mm; tolerances on dimensions, shape and mass as specified in EN 10029 with thickness tolerance class A and normal flatness tolerance in process route 1D (see Table 6), inspection document 3.1.B as specified in EN 10204: 10 plates EN 10029 - 8A 2 000 5 000 Steel EN 10028-

39、lled Copy, (c) BSI Page 7 EN 10028-7:2000 8.3 Chemical composition and chemical corrosion properties 8.3.1 The chemical composition requirements given in Tables 1 to 4 apply in respect of the chemical composition according to the cast analysis. 8.3.2 The product analysis may deviate from the limitin
40、g values for the cast analysis given in Tables 1 to 4 by the values listed in Table 5. 8.3.3 Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic steels the specifications in Tables 7, 9 and 10 apply. NOTE 1: EN ISO 3651-2 i
41、s 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 not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available experience of the use of
42、 the steels. 8.4 Mechanical properties 8.4.1 The tensile properties at room temperature and the impact energy at room and at low temperatures as specified in Tables 7 to 10 apply for the relevant specified heat treatment condition. NOTE: Austenitic steels are insensitive to brittle fracture in the s
43、olution annealed condition. Because they do not have a pronounced transition temperature, which is characteristic of other steels, they are also useful for application at cryogenic temperatures. 8.4.2 The values in Tables 11 to 14 apply for the 0,2 % and 1,0 % proof strength at elevated temperatures
44、. Additionally, the values in Table 15 apply for the tensile strength at elevated temperatures. Tensile strength values at elevated temperatures for austenitic-ferritic steels are given for guidance in annex D. 8.4.3 Annex E gives mean values as preliminary data for the purchaser about creep strengt
45、h and creep rupture. These data apply for the solution annealed condition only. 8.4.4 In annex F preliminary data on mechanical properties at low temperatures of austenitic steels are listed. 8.5 Surface condition See EN 10028-1 and Table 6. 8.6 Internal soundness See EN 10028-1. 8.7 Physical proper
46、ties Reference data on some physical properties of austenitic creep resisting steels are given in annex A. For other stainless steels, see annex A of EN 10088-1.
