Abstract
The present invention relates to a hot-rolled steel strip for further processing to form non-grain oriented electrical sheet with the following composition (in % by weight) C: <0.02%, Mn: ≦1.2%, Si: 0.1-4.4%, Al 0.1-4.4%, wherein the sum formed from the Si content and twice the Al content is <5%, P: <0.15%, Sn: ≦0.20%, Sb: ≦0.20%, the remainder iron and unavoidable impurities, with a strip thickness which is at most 1.8 mm, and with a partially softened structure which is characterised by a high intensity for the α fibre (fibre representation of orientation distribution functions) in the region of 0° to 60°, wherein the ratio I/Iformed from the intensity Iof the position (112) <110> to the intensity Iof the position (001) <110> is >0.4 and the ratio I/Iformed from the intensity Iof the position (111) <110> to the intensity Iof the position (001) <110> is >0.2.
