Non Oriented Electric Steel Sheet And Method For Manufacturing Non Oriented Electric Steel Sheet
Abstract: A non-oriented electric steel sheet characterized in that, in a cross section in the plate thickness direction of a base material, the number density N2-5 of precipitates having an equivalent circle diameter of 50-500 nm present in a range of 2.0-5.0 µm in the plate thickness direction from the surface of the base material is 0.30/µm2 or less, and the relationship between the number density N2-5 and the number density N0-2 of precipitates having an equivalent circle diameter of 50-500 nm present in a range of 2.0 µm from the surface of the base material satisfies formula (1). (N2-5)/(N0-2)<0.5 ··· Formula (1)
