28、led and skin passed (+A or +LC); cold rolled (+CR); quenched and tempered (+QT). 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
29、Chemical composition 7.4.1 Cast analysis The chemical composition shall be in accordance with the 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 in

For information, the
32、 minimum hardness values given in Table A.2 show the minimum values after quenching, without tempering. NOTE 3 For spring applications, the preferred hardness range (HV) for steels according to Table 3 in the quenched and tempered condition are given in Table A.3 for information. 7.5.2 Bend test Req
33、uirements for the bend test for steels in the annealed condition (+A) may be agreed at the time of enquiry and order. 7.6 Structure 7.6.1 Grain size See EN 10132-1. 7.6.2 Non-metallic inclusions See EN 10132-1. 7.6.3 Decarburization For silicon alloyed steels, decarburization shall not exceed 3 % of
34、 the material thickness per side, for non-silicon alloyed steels, decarburization shall not exceed 2 % 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 narrow steel strip shall be br
35、ight as produced 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; brigth tempered: unpolished; polished: obtained by fine grinding, abrasive brushing or other processes; polished a
36、nd coloured: blue or yellow colour obtained by oxidization by heat treatment. 7.8 Dimensions and tolerances on dimensions and shape See EN 10132-1. 8 Inspection See EN 10132-1.Page 7 EN 10132-4:2000 BSI 05-2000 9 Sampling See EN 10132-1. 10 Test methods See EN 10132-1. 11 Labelling, packaging and pr
