Abstract (en)

[origin: EP0585956A1] A grain-oriented electrical steel sheet comprising 2.5 - 4.5 % Si by weight and measuring 0.36 - 1.00 mm in thickness is imparted with a good core loss value for its thickness by controlling its C content, flux density, grain boundary configuration, and deviation degree of crystal orientation in the grains. <IMAGE>
