NOTEEN10020 applies with respect to non alloy steel definition with the exception of copper content (see7.3.2). 4 Information to be supplied by the purchaser 4.1 General The following information shall be supplied by the purchaser, at the time of the enquiry and order: a) details of

31、the product form, length, quantity and any further processing work that is required, e.g.surface treatment; b) the designation of the product (in accordance with6.2); c) whether products have to be submitted to inspection and testing and if inspection and testing is required, which type of inspectio

32、n and which inspection document is required (see8.1.2). Where non specific choice is made by the purchaser concerninga) andb) the supplier shall refer back to the purchaser. NOTEIt is recommended that the manufacturer be informed by the purchaser at the time of the order, if the purchaser intends to

33、 carry out any surface treatment on the product after delivery. 4.2 Options A number of options are specified in clause10. In the event that the purchaser does not indicate a requirement to implement any of these options, the product shall be supplied in accordance with the basic specification. 5 Ma

34、ss of steel The calculated mass shall be determined using a conventional volumetric mass of7,85kg/dm 3 . 6 Classification and designation 6.1 Classification This European Standard specifies six steel grades which are classified as non-alloyed steels according to EN10020. 6.2 Designation 6.2.1 Steel

35、names 2)are assigned to steel grades in Table 1 and Table 2 in accordance with EN10027-1 and IC10. Steel numbers are allocated to steel grades in accordance with EN10027-2. 6.2.2 The products covered by this European Standard shall be designated in the following sequence: a) the name of the product,

36、 i.e.“Sheet piling”; 1) Until these Euronorms are transformed into European Standards, they may be either implemented as referenced in this European Standard or the corresponding national standards given in Annex B may be implemented in their place. 2) Former national designations (steel names) are

37、listed in Annex CEN10248-1:1995 4 BSI 12-1999 b) the number of this European Standard, i.e.EN10248; c) the steel name or number. EXAMPLE: Sheet piling EN10248-S320GP or Sheet piling EN10248-1.0046, indicating a sheet piling product in accordance with EN10248 made of steel S320GP (steel number1.0046)

38、. 7 Technical requirements 7.1 Steel manufacturing process 7.1.1 The steel manufacturing process shall be at the manufacturers option. Where specified at the time of the enquiry and order, the steel manufacturing process shall be reported to the purchaser. Option1, see10.2. 7.1.2 The method of deoxi

39、dation shall be at the option of the manufacturer, except that rimming steel shall not be permitted. 7.2 Delivery condition Unless otherwise agreed, sheet piles shall be delivered in the as rolled condition. Option2, see10.3. 7.3 Chemical composition 7.3.1 The upper limits applicable for both the la

40、dle and the product analysis shall comply with the values given in Table 1. 7.3.2 Where specified at the time of the enquiry and order, the copper content can be between0,20% and0,35% or0,35% and0,50%. Option3, see10.4. 7.3.3 A maximum carbon equivalent value (CEV) based on the ladle analysis may be

41、 agreed at the time of the enquiry and order. The carbon equivalent value shall be determined according to the following formula: Where a carbon equivalent value is agreed the content of the elements in the carbon equivalent formula shall be reported in the inspection document (see8.8). Option4, see

42、10.5. 7.4 Mechanical properties 7.4.1 Under the inspection and testing conditions as specified in clause8 and in the delivery condition as specified in7.2, the mechanical properties shall comply with the relevant requirements of Table 2. 7.4.2 If agreed at the time of the enquiry and order, all stee

43、l grades shall be supplied with specified impact properties. Option5, see10.6. 7.5 Technological properties 7.5.1 Weldability 7.5.1.1 In general, steel sheet pile grades are suitable for arc welding. 7.5.1.2 Steels specified in this European Standard do not have unlimited suitability for the various

44、 welding processes, since the behaviour of a steel during and after welding depends not only on the material, but also on the dimensions and shape and on the manufacturing and service conditions of the components. NOTE 1With increasing product thickness, increasing strength level and increasing carb

45、on equivalent value the occurrence of cold cracking in the welded zone forms the main risk. Cold cracking is caused by the following factors in combination: a) the amount of diffusible hydrogen in the weld metal; b) brittle structure of the heat affected zone; c) significant tensile stress concentra

46、tions in the welded joint. NOTE 2When using recommendations in any relevant national standard, the recommended welding conditions and the various welding ranges of the steel grades may be determined depending on the product thickness, the applied welding energy, the design requirements, the electrod

47、e efficiency, the welding process and the weld metal properties. NOTE 3For high stress welded constructions, steels with appropriate properties may be agreed at the time of the enquiry and order. Option4, see10.5. 7.5.2 Other requirements Where specified at the time of the enquiry and order, the sui

48、tability and the relevant product quality requirements for hot dip zinc coating may be agreed. Option6, see10.7. Where specified at the time of the enquiry and order, the interlock strength may be agreed 3) Option7, see10.8. CEVC Mn 6 - CrMoV + 5 - NiCu + 15 - + = 3) Both the specified value of the

49、interlock strength and the relevant test method shall be agreedEN 10248-1:1995 BSI 12-1999 5 Table 1 Chemical composition of the ladle and product analysis for hot rolled steel sheet piling aDesignation EN10027 Classification EN10020 b Chemical composition % max e Steel name Steel number C Mn Si P S N cd Ladle Product Ladle Product Ladle Product Ladle Product Ladle Product Ladle Product S240GP S270GP S320GP S355GP S390GP S430GP 1.0021 1.0023 1.0046 1.0083 1.0522
