Abstract

A non-oriented magnetic steel sheet that contains, bv mass, up to 0.005% carbon, 2 - / % silicon, 0.03-3% manganese, up to 3% aluminum, up to 0.2% phosphorus, up to 0.005% sulfur, up to 0.005% nitrogen, 0.0001- 0.0005% selenium, and 0.0005-0.005% arsenic, with the remainder comprising iron and unavoidable impurities. Said non-oriented magnetic steel sheet exhibits an iron loss (W15/50) of no more than 3.5 W/kg when excited with 1.5 T at 50 Hz and exhibits excellent iron-loss characteristics prior to a punching process in which the quotient (x/t) of the amount of sag (x, in mm) that occurs when the steel sheet is punched and the thickness (t, in mm) of the sheet is less than or equal to 0 . 15. Furthermore, the degradation in iron-loss characteristics ：from the punching process is minimal.
