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of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. This document supersedes EN 10028-7:2000. 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 97/23/EC. For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. The steel grades covered by this European Standard have been selected from EN 10088-1. EN 10028 consists of the following parts under the general title Flat products made of steels for pressure purposes: -Part 1: General requirements -Part 2: Non-alloy and alloy steels with specified elevated temperature properties -Part 3.· Weldable fine grain steels, normalized -Part 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 -Part 7: Stainless steels NOTE The clauses marked by tvvo points ( of enquiry and order. ) contain information relating to agreements that may be made at the time According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 3 EN 10028-7:2007 (E) 1 Scope 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 Standard have been selected from EN 10088-1. NOTE 2 Once this European Standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials 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 the ESRs of the Pressure Equipment Directive are satisfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document.

Shall be according to EN 10028-1 . 7.2 Options A number of options are specified in this document and listed below. Additionally, the relevant options of EN 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 products shall be supplied in accordance with the basic specification (see EN 10028-1). a) mechanical properties for increased product thicknesses (see Table 7, footnote e); b) higher Rp0,2 and Rp1 ,0 values for continuously hot rolled products (see Table 9, footnote d and Table 10, footnote b). 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 10029 with thickness tolerance class A and \"normal\" flatness tolerance according to process route 1 D (see Table 6), inspection document 3.1 as specified in EN 10204: 10 plates-EN 10029-8Ax2000x5000-steel EN 10028-7-X5CrNi18-10+1 D-inspection document 3.1 or 10 plates-EN 10029-8Ax2000x5000-steel EN 10028-7-1.4301+10-inspection document 3.1 8 8.1 Requirements Steelmaking process Shall be according to EN 10028-1. 5 EN 10028-7:2007 (E) 8.2 Delivery condition The products shall be supplied in the delivery condition specified in the order by reference to the process route given in Table 6 and, where alternatives exist, to the treatment 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 Table 1 to 4 shall apply in respect of the chemical composition according to the cast analysis. 8.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Table 1 to 4 by the values listed in Table 5. 8.3.3 The specification in Tables 7, 9 and 10 shall apply in respect to resistance to 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 steel 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 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 1O 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 % and 1.0 % proof strength at elevated temperatures. 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 C. 8.4.3 Annex D gives mean values as preliminary data for the purchaser about strength for 1 % (plastic) Creep strain and creep rupture. These data apply for the solution annealed condition only (see Table A.3). 8.4.4 In Annex E preliminary data on mechanical properties at low temperatures of austenitic steels are listed. 8.5 Surface condition Shall be according to EN 10028-1 and Table 6. 8.6 Internal soundness Shall be according to EN 10028-1. 8.7 Physical properties For reference data on physical properties, see Annex A of EN 10088-1 :2005. 6 EN 10028-7:2007 (E) 8.8 Post weld heat treatment Guidelines for the purchaser on post weld heat treatment are given in Annex B. 9 Inspection 9.1 Types of inspection and inspection documents Shall be according to EN 10028-1. 9.2 Tests to be carried out Shall be according to Table 16 and EN 10028-1. 9.3 Re-tests Shall be according to EN 10028-1. 10 Sampling 10.1 Frequency of testing Shall be according to Table 16 and EN 10028-1. 10.2 Selection and preparation of samples and test pieces Shall be according to EN 10028-1. 11 Test methods Shall be according to EN 10028-1. 12 Marking Shall be according to EN 10028-1. 7EN 10028-7:2007 (E) Table 1 -steel grade Steel narre Chemical composition (cast analysis)• offerritic steels %bymass steel number 1.4003 1.4516 1.4520 1.4510 1.4513 1.4521 1.4526 1.4509 c max 0.03J 0.08 O.D25 0.05 O.D25 O.D25 0.08 0.03J Si max 1.00 0.70 0.50 1.00 1.00 1.00 1.00 1.00 Mn max 1.50 1.50 0.50 1.00 1.00 1.00 1.00 1.00 p max 0.040 0.040 0.040 0.040 0.040 0.040 0.040 0.040 s max 0015 0.015 0015 0015 0015 0015 0.015 0015 N max 0.030 Cr 10.5to 12.5 10.5to 12.5 16.0to 18.0 16.0to 18.0 16.0to 18.0 17.0to 20.0 16.0to 18.0 17.5to18.5 Mo Nb Ni 0.30to 1.00 0.50to 1.50 Ti X2CrNi12 X6CrNiTi12 X2CrTi17 X3CrTi17 X2CrMo1i17-1 X2CrMo1i18-2 X6CrMoNb17-1 X2CrTiNb18 -O.D15 -0.020 0.030 0.040 ----0.80to 1.40 1.80to 2.50 0.80to 1.40 ------[7'(C•N)+0.10] to 1.00 (3'C+0.3J) to 1,00 -0.05to 0.35 0.30to 0.60 [4'(C•N)+0.15] to 0.80' 0.30to 0.60 [4'(C+N)+0.15] to 010' ---------0.10to 0.60 • Elements not listed in this tab le sha II not be intentionally added to the stee I without the ag re eme nt of the purchaser except for finishing of the cast.

A.2 Flame cutting may adversely affect edge areas; they should be machined. A.3 Scale and annealing colours produced during hot forming, heat treatment or welding may adversely affect the corrosion resistance. They should be removed as far as possible before use, e.g. by pickling. A.4 For further information see EN 1011-3 [1]. 31 EN 10028-7:2007 (E) Annex B ( informative) Post weld heat treatment B.1 In general, welded assemblies of stainless steels covered by this European Standard are not subjected to any heat treatment with the following exceptions: --martensitic grades are retempered and ferritic grades are reannealed if there is any risk of residual martensite in the heat affected zone; for appropriate temperatures see Tables A.1 and A.2. B.2 During heating of high chromium and molybdenum austenitic-ferritic or austenitic steel weldments containing some ferrite, intermetallic phases may be formed which need to be re-dissolved during post weld heat treatment. As most filler metals are overalloyed in comparison with the equivalent basic grades, minimum solution temperatures higher than those given in Tables A.3 and A.4 may be necessary. In the case of fully austenitic weld structures it should be verified that mechanical properties of heat treated weldments conform to this European Standard. Oxidation of surfaces which necessitates pickling, and possible distortion of the welded construction may raise further difficulties. Consequently post weld heat treatment of duplex and austenitic steels should be avoided, and therefore welding be planned carefully. B.3 In special cases, e.g. for parts with greater wall thickness, requirements concerning stress-relief and resistance to intergranular corrosion, in order to avoid failure by stress corrosion cracking or corrosion fatigue, may prove the necessity for post weld heat treatment. This should be carried out according to Table B.1 by holding at an intermediate stage below the usual solution temperature (see Table A.3) and is defined as stabilizing annealing for the niobium or titanium bearing grades and as stress-relieving for the un-stabilized low carbon grades. In some cases post weld heat treatment may also be performed as solution annealing according to Table A.3 or at a temperature below the precipitation range of carbides and intermetallic phases; however, the latter reduces only peak stresses. B.4 Preheating of austenitic-ferritic steels is a very effective precaution against stress increase by shrinkage of thicker welded cross-sections, because temperatures of 200'C to 250'C bring down room temperature yield strength by about 50 %. Thus preheating is often more appropriate to avoid high stress levels in those weldments than any post weld heat treatment, and a preheating temperature between 120'C and 200'C according to the particular steel and thickness should be applied.

According to experience with long-time creep-testing it seems apparent that scattering of data is about ±20 % in the long-range endurance of about 10h up to 700\"C to 800\"C. Above that temperature, scattering may be gradually more or less enlarged and be summarized with about 35% to 40% at 1 OOO\"C testing temperature. Hovvever, individual deviations need to be presumed. 5 NOTE 2 The strength values for 1 % (plastic) creep strain and creep rupture given up to the elevated temperatures listed in Tables D.1 and D.2 do not mean that the steels can be used in continuous duty up to these temperatures. The governing factor is the total stressing during operation. Where relevant it is important that the oxidation conditions are taken into account. 35 EN 10028-7:2007 (E) Table D.1 -Strength for 1 % (plastic) creep strain of austenitic creep resisting steels in
