It is recommended that the manufacturer be informed by the purchaser at the time of the order, if the purchaser intends to carry out any surface treatment on the product after delivery. 4.2 Options A number of options are specified in clause 10. In the event that the

23、purchaser does not indicate a requirement to implement any of these options, the product shall be supplied in accordance with the basic specification. 5 Mass of steel The calculated mass shall be determined using a conventional volumetric mass of 7,85 kg/dm3. 6 Classification and designation 6.1 Cla

24、ssification This European Standard specifies six steel grades which are classified as non-alloyed steels according to EN 10020. )Until these Euronorms are transformed into European Standards, they may be either implemented as referenced in this European Standard or the corresponding national standar

25、ds given in annex B may be implemented in their place. O BSI 1996 (EN EN*lI024-L 95 3404587 0320673 130 Page 4 EN 10248-1 : 1995 6.2 Designation 6.2.1 Steel names2) are assigned to steel grades in tables 1 and 2 in accordance with EN 10027-1 and IC 10. Steel numbers are allocated to steel grades in

26、accordance with EN 10027-2. 6.2.2 The products covered by this European Standard shall be designated in the following sequence : a) the name of the product, i.e. Sheet piling; b) the number of this European Standard, i.e. EN 10248; c) the steel name or number. EXAMPLE: Sheet piling EN10248-S320GP or

27、 Sheet piling EN 10248-1.0046, indicating a sheet piling product in accordance with EN 10248 made of steel S320GP (steel number 1.0046). 7 lkchnical 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

28、 the enquiry and order, the steel manufacturing process shall be reported to the purchaser. Option 1, see 10.2. 7.1.2 The method of deoxidation 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 sh

29、all be delivered in the as rolled condition. Option 2, see 10.3. 7.3 Chemical composition 7.3.1 The upper limits applicable for both the ladle 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

30、 between 0,20 % and 0,35 % or 0,35 % and 0,50 %. Option 3, see 10.4. 7.3.3 A maximum carbon equivalent value (CEV) based on the ladle analysis may be agreed at the time of the enquiry and order. The carbon equivalent value shall be determined according to the following formula: Mn Cr + Mo + V Ni + C

31、u 15 + 5 CEV=C+- + 6 )Former national designations (steel names) are listed in annex C Where a carbon equivalent value is agreed the content of the elements in the carbon equivalent formula shall be reported in the inspection document (see 8.8). Option 4, see 10.5. 7.4 Mechanical properties 7.4.1 Un

32、der the inspection and testing conditions as specified in clause 8 and in the delivery condition as specified in 7.2, 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 steel grades shall be supplied with specif

33、ied impact properties. Option 5, see 10.6. 7.5 “kchnological properties 7.5.1 Weldabilitg 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 welding processes, since the behavi

34、our 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 1. With increasing product thickness, increasing strength level and increasing carbon equivalent value the occurrence

35、 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 concentrations in the welded joint. NOlE 2.

36、 When 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 electrode efficiency, the welding proces

37、s and the weld metal properties. NCYE 3. For high stress welded constructions, steels with appropriate properties may be agreed at the time of the enquiry and order. Option 4, see 10.5. 7.5.2 Other requirements Where specified at the time of the enquiry and order, the suitability and the relevant pr

38、oduct quality requirements for hot dip zinc coating may be agreed. Option 6, see 10.7. Where specified at the time of the enquiry and order, the interlock strength may be agreed3) Option 7, see 10.8. 3)J30th the specified value of the interlock strength and the relevant test method shall be agreed O
