Delivery condition
8.2.1 Unless otherwise agreed at the time of enquiry and order, the products covered by this European 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, additional 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,
exceeds 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 document can still be regarded as valid.
8.3 Chemical composition 8.3.1 The requirements of Table 1 shall apply for the chemical composition 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 may be agreed upon at the time of enquiry and order for steel grades P235GH, P265GH, P295GH and P355GH. In this case, the following formula shall apply for calculation of the carbon equivalent value (CEV): 15CuNi5VMoCr6MnCCEV++++++=SIST EN 10028-2:2009
