Zusammenfassung:	OF THE DISLCOSURE: A method for producing a silicon bearing steel strip for electro magnetic applications. This method comprises the steps of hot rolling to sheet a slab having by weight, 2% to 4% of silicon 0.05% to 0.1% of manganese, 0.02% to 0.035% of sulphur, 0.02% to 0.06% of carbon, 0.002% to 0.01 of nitrogen, and 0.01% to 0.1% of vanadium, together with incidental impurities, and cold rolling the hot band with a final reduction of at least 70% before decarburising at a temperature within the range 900 to 1050.degree.C. Advantageously, the magnetic properties of the strip derived from the abovelisted, starting material may be up-grated by suitable selection of the process parameters.
