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 characterised by increased strength and good magnetic properties. |
