21、283:2017EN 10028-3:2017 (E) 3 European foreword This document (EN 10028-3:2017) has been prepared by Technical Committee ECISS/TC 107 “Steels for pressure purposes”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publicatio
22、n of an identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall
23、not be held responsible for identifying any or all such patent rights. This document supersedes EN 10028-3:2009. 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 Directive 2014/68/E
24、U. For relationship with Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document. A list of changes between this document and the previous version can be found in Annex C. According to the CEN-CENELEC Internal Regulations, the national standards organizations of th
25、e following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherl
26、ands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 100283:2017EN 10028-3:2017 (E) 4 1 Scope This European Standard specifies requirements for flat products for pressure equipment made of weldable fine grain steels as
27、specified in Table 1. NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with EN ISO 643. The requirements and definitions of EN 10028-1:2017 also apply. NOTE 2 Once this European Standard is published in the EU Official Journal (OJEU
28、) 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 materials in this European Standard (Part 1 and the other relevant part of the series) and does not presume adequacy of the material to a specif
29、ic 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 satisfied, needs to be done. 2 Normative references The following documents
30、, 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.

N), b) elevated temperature
34、quality (P.NH), c) low temperature quality (P.NL1) and d) special low temperature quality (P.NL2). 6.1.2 The grades P275NH to P355NL2 are alloy quality steels, the grades P275NL2 and the grades P420NH to P460NL2 are alloy special steels. 6.2 Designation See EN 10028-1:2017. 7 Information to be suppl

Additionally the relevant options of EN 10028-1:2017 apply. If the purchaser does not indicate a wish to implement any of these options at the time of
36、enquiry and order, the products shall be supplied in accordance with the basic specification (see also EN 10028-1:2017). 1) tests in the simulated normalized condition (see 8.2.2); 2) delivery of products in the untreated condition (see 8.2.3); 3) maximum carbon equivalent value (see 8.3.3); 4) no o
37、ption, intentionally left blank; 5) modified values for ReHand Rmfor grades P460NH and P460NL1 (see Table 4, footnote a); 6) application of the Rp0,2values of Table 5 for the corresponding P.NL1 and PNL2 grade (see 8.4.2); 7) no option, intentionally left blank; 8) specification of a minimum impact
38、energy of 40 J (see 8.4.1 and Table 6); 9) HIC test in accordance with EN 10229 (see 8.7); 10) mid thickness test pieces for the impact test (see Clause 10); 11) verification of impact energy for longitudinal test pieces (see Clause 11); 12) use of test solution B for the HIC test with agreed accept

For steels with minimum yield strength 420 MPa, delayed cooling or additional tempering ma
42、y be necessary for small product thicknesses and in special cases. If such a treatment is performed, this shall be noted in the inspection document. 8.2.2 Normalizing may, at the discretion of the manufacturer, be replaced with normalizing rolling for all steel grades covered by this standard. In th
43、is case, additional tests on simulated normalized samples with an agreed frequency of testing may be agreed at the time of enquiry and order to verify that the specified properties are complied with. 8.2.3 If agreed at the time of enquiry and order, products covered by this document may also be deli
44、vered in the untreated condition. In these cases, testing shall be carried out in the simulated normalized condition (but see 8.2.1). 8.2.4 Information on welding are given in Annex B of this standard. 8.3 Chemical composition 8.3.1 The requirements of Table 1 shall apply for the chemical compositio
45、n according to the cast analysis. 8.3.2 The product analysis shall not deviate from the specified values for the cast analysis as specified in Table 1 by more than the values given in Table 2. 8.3.3 A maximum value for the carbon equivalent in accordance with Table 3 may be agreed at time of enquiry
