30、nd tempered (+QT) - for the grades indicated in Table 3 of this standard. NOTE The delivery condition - annealed to achieve spheroidized carbides (+AC) - may be agreed. In such cases, limits on spheroidization and mechanical properties may also be agreed at the time of enquiry and order. 7.4 Chemica
31、l composition 7.4.1 Cast analysis The chemical composition shall be in accordance with the values specified in Table I for the cast analysis. 7.4.2 Product analysis In cases where a product analysis is requested, the admissible deviations from the values specified for the cast analysis are indicated
32、 in Table 2. 7.5 Mechanical properties The mechanical properties of the strip shall be in accordance with the values given in Table 3. For thicknesses outside this range, mechanical properties shall be agreed between the customer and the supplier. NOTE I For those customers who specify Rockwell hard
33、ness rather than Vickers hardness or tensile strength, a table is given in A.l , showing Rockwell hardness values for information. NOTE 2 For information, the minimum hardness values given in Table A.2 show the minimum values after quenching, without tempering. OBSI 05-2000 COPYRIGHT European Commit

The surface finishes of quenched and tempered
36、cold rolled strip are as follows: - grey/blue oxide finish: unpolished; - bright tempered: unpolished; - polished: obtained by fine grinding, abrasive brushing or other processes; - polished and coloured: blue or yellow colour obtained by oxidization by heat treatment. 7.8 Dimensions and tolerances
37、on dimensions and shape Tolerances on width for quenched and tempered strip shall be agreed between customer and supplier. For all other tolerances EN 10140 applies (see also EN 10132-1).
