Non Oriented Electromagnetic Steel Sheet

Abstract: The present invention pertains to a composition that may undergo a-? transformation. The composition contains 0.0010-0.0050% of Ti. When a surface of a steel sheet is measured using a scanning electron microscope with electron backscatter diffraction (SEM-EBSD) and if the area ratio of crystal grains in a {hkl} orientation (tolerance: within 10°) with respect to the entire visual field is represented by Ahkl-uvw, A411-011 is at least 15%, and the number density of deposits is 0.5-50 pieces/µm2.
