Abstract:
A non-oriented electrical steel sheet having outstanding magnetic properties and i, as percentages by weight, from 0.7˜3.02.5% of Al, 0.2˜32.5% of Si, 0.2˜2.01.5% of Mn, 0.001 0005˜0.004% of N, 0.0005˜0.004% of S, 0.003% or less of C, and a balance of Fe and other unavoidably incorporated impurities, wherein the Al, Mn, N and S are included so as to satisfy the compositional formulae 1≤{[Al]+[Mn]}≤3.5, 0.002≤{[N]+[S]}≤0.006, 300250≤{([Al]+[Mn])/([N]+[S])}≤1,400, 1.4≤{[Al]+[Si]+[Mn]/2}≤5.5, 1 [Al]/[Si]≤7.5, 1≤[Al]/[Mn]≤3.7; and a production method therefor. By optimising the Al, Si, Mn, N and S added components, the distribution density of coarse inclusions is increased, thereby improving the crystal-grain growth properties and domain wall motility and producing the highest grade of non-oriented electrical steel sheet having superior magnetic properties, low hardness, and superior customer workability and productivity.

Claim (Index 9):
The non-oriented electrical steel sheet of  claim 1 , wherein a cross-sectional Vickers hardness (Hv1) is 190 or less.
