28、very condition Cold rolled narrow steel strip covered by EN 10132-3 shall be supplied in one of the following delivery conditions: annealed or annealed and skin passed (+A or +LC); cold rolled (+CR); quenched and tempered (+QT) - for the grades indicated in Table 3 of this standard. NOTE The deliver

29、y 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 Chemical composition 7.4.1 Cast analysis The chemical composition shall be in accordance with the

30、 values specified in Table 1 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 in Table 2. 7.5 Mechanical properties The mechanical properties of the strip shall be in

31、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 1 For those customers who specify Rockwell hardness rather than Vickers hardness or tensile strength, a table is given in A.1, showing Ro

32、ckwell 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.Page 6 EN 10132-3:2000 BSI 07-2000 7.6 Structure 7.6.1 Grain size See EN 10132-1. 7.6.2 Non-metallic inclusions See EN 10132-1. 7.

33、6.3 Decarburization For steels with minimum carbon contents 0,50 %, decarburization shall not exceed 3 % of the material thickness per side when measured at a distance of 5 mm from the strip edge (see also EN 10132-1). 7.7 Surface finish The surface finish of cold rolled steel strip shall be bright

34、as achieved by rolling and annealing in a controlled atmosphere. The surface finishes of quenched and tempered 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 co

35、loured: blue or yellow colour obtained by oxidization by heattreatment. 7.8 Dimensions and tolerances 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). Special ed

36、ges are available by agreement between supplier and customer, and the tolerances on width for these edges are to be agreed. 8 Inspection See EN 10132-1. 9 Sampling See EN 10132-1. 10 Test methods See EN 10132-1.Page 7 EN 10132-3:2000 BSI 07-2000 11 Labelling, packaging and protection See EN 10132-1.
