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 also EN 10028-1). a) lower copper content and maximum tin content (see Table 1, footnote b); b) minimum chromium content of 0,80% (see Table 1, footnote f); c) maximum carbon content of 0,17% for product thicknesses greater than 150 mm (see Table 1, footnote g); d) tests in the simulated normalized condition (see 8.2.2); e) delivery conditions deviating from those specified in Table 3 (see 8.2.2 and 8.2.3); f) maximum carbon equivalent value for P235GH, P265GH, P295GH and P355GH (see 8.3.3); g) HIC test in accordance with EN 10229 (see 8.7); h) step cooling test in accordance with annex E (see 8.8); i) mid thickness test pieces for the impact test (see clause 10); j) mechanical properties for product thicknesses > 250 mm (see Table 3, footnote a); k) specification of the delivery condition +QT where the usual delivery condition is +NT (see Table 3, footnote c and Table 4, footnote c); l) additional impact energy values (see Table 3, footnote f); m) Rp0,2 values at elevated temperature for increased product thicknesses (see Table 4, footnote b). 7.3 Example for ordering 10 plates with nominal dimensions, thickness = 50 mm, width = 2 000 mm, length = 10 000 mm, made of a steel grade with the name 16Mo3 and the number 1.5415 as specified in EN 10028-2, to be delivered untreated, inspection document 3.1.B as specified in EN 10204: 10 plates – 50 x 2 000 x 10 000 – EN 10028-2 16Mo3+AR - Inspection document 3.1.B or 10 plates – 50 x 2 000 x 10 000 – EN 10028-2 1.5415+AR – Inspection document 3.1.B Copyright British Standards Institution Reproduced by IHS under license with BSI - Uncontrolled Copy Document provided by IHS Licensee=Bureau Veritas/5959906001, 11/08/2004 18:27:14 MST Questions or comments about this message: please call the Document Policy Group at 303-397-2295. - - ` , , , ` , ` ` , , ` , ` , ` ` ` , ` , , ` , ` ` ` ` ` - ` - ` , , ` , , ` , ` , , ` - - - EN 10028-2:2003 (E) 6 8 Requirements 8.1 Steelmaking process See EN 10028-1. 8.2 Delivery condition 8.2.1 Unless otherwise agreed at the time of enquiry and order, the products covered by this standard shall be supplied in the usual conditions given in Table 3 (see 8.2.3). 8.2.2 �� Normalizing may, at the discretion of manufacturer, be replaced with normalizing rolling for the steel grades P235GH, P265GH, P295GH and P355GH. In this case, tests in the simulated normalized condition 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 so agreed at the time of enquiry and order, products made of steel grades P235GH, P265GH, P295GH, P355GH and 16Mo3 may also be delivered in the untreated condition. Products made of one of the other alloy grades may be supplied in the tempered or normalized condition or, in exceptional cases, in the untreated condition if so agreed (Annex A contains heat treatment information for the purchaser). In these cases, testing shall be carried out on test pieces in the usual delivery condition as indicated in Table 3. NOTE The testing of the test pieces in a simulated heat treated condition does not discharge the processor from the obligation of providing proof of the specified properties in the finished product. 8.2.4 Information on welding is given in EN 1011-1 and EN 1011-2. NOTE Excessive post weld heat treatment (PWHT) conditions can decrease the mechanical properties. When in stress relieving the intended time temperature parameter P = Ts (20 + lg t) � 10-3 , where Ts is the stress relieving temperature in K and t is the holding time in hours, is exceeding the critical (Pcrit.) values in annex B, the purchaser should in his enquiry and order inform the manufacturer accordingly and, where appropriate, tests on simulated heat treated samples can be agreed to check whether after such a treatment the properties specified in this European Sta
