Abstract

Disclosed is a non-oriented electromagnetic steel plate having a low high-frequency iron loss. The non-oriented electromagnetic steel plate has an aluminum concentration gradient in the thickness-wise direction and is characterized in that the whole steel plate comprises, by mass, C: not more than 0.005%, Si: 2% to 4%, Mn: not more than 1%, and Al: 0.1% to 8% with the balance consisting of Fe and unavoidable impurities and the concentration of Al (% by mass) in the direction of the thickness of the plate satisfies the following formula (1). 0.1 s-Xc)/t < 100 (1) where Xs: concentration of Al at the surface of the steel plate, % by mass; Xc: concentration of Al at the center of the steel plate, % by mass; and t: depth from the surface of the steel plate at which the concentration of Al (% by mass) is Xc + 0.05(Xs - Xc), mm.
