Method of estimating mechanical hardness of steel from its magnetic

A method for producing a non-silicon steel for electro magnetic applications includes the steps of producing a vacuum de-gassed steel melt containing less than 0.025% by weight of carbon, between 0.1% and 1.0% of manganese, between 0.01% and 0.15% phosphorus, not more than 0.02% of sulphur, not more than 0.007% of nitrogen, with titanium within the range of 0.05% to 0.25%, the reminder being iron, except for incidental impurities, hot rolling slab derived from the melt, using a finishing temperature within the range 900.degree. C. to 950.degree. C. and coiling the resulting hot rolled strip at a temperature of not less than 700.degree. C.

Electro magnetic steels

A method for producing non-oriented steel for electromagnetic applications comprises hot rolling a steel containing a nitride/carbide former and coiling the hot band at a temperature of not less than 680.degree. C. before cold reduction and annealing in a non-decarburizing atmosphere.
