Non Oriented Electromagnetic Steel Sheet

Abstract: The component composition of the non-oriented electromagnetic steel sheet according to the present invention contains the following, in mass%: C : 0.0005 to 0.0030%, Si : 1.5 to 3.5%, Al : 0.10 to 2.00%, Mn : 0.1 to 2.0%, P : not more than 0.180%, S : 0.0005 to 0.0030%, N : 0.0005 to 0.0030%, Ti : 0.0005 to 0.0030%, B : 0 to 0.0020%, and Sn + 2 x Sb : 0 to 0.25%, with the balance being Fe and impurities. The non-oriented electromagnetic steel sheet according to the present invention also satisfies 2 = A = 10, 1.0 = B = 10, and 0.8 = B/A = 1.0 where: t is the sheet thickness; A is the strength of the crystal orientation {111}<112> orientation measured at a position in the range from 2/5t to 3/5t; and B is the strength of the {100}<012> orientation measured at a position in the range from 2/5t to 3/5t.
