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
