Abstract
A non-grain-oriented electrical steel strip or sheet consisting of a steel which contains, in addition to iron and unavoidable impurities, (in wt. %) Si: 1.0-4.5%, Al: up to 2.0%, Mn: up to 1.0%, C: up to 0.01%, N: up to 0.01%, S: up to 0.012%, Ti: 0.1-0.5% P: 0.1-0.3%, wherein 1.0≦% Ti/% P≦2.0 applies for the % Ti/% P ratio. The NGO sheet or strip can be manufactured by cold rolling a hot strip of a steel having the previously mentioned composition into a cold strip and subjecting this cold strip to a final annealing process. Different variants of this final annealing process may be used to accentuate the properties of the strip or sheet. The non-grain-oriented electrical steel strip or sheet and components manufactured from such a sheet or strip for electrotechnical applications are characterized by increased strength and good magnetic properties.
