Abstract:
There is produced a molten steel containing, in mass %, Si: not less than 0.1% nor more than 7.0%, Mn: 0.1% or more, Al: not less than 0.2% nor more than 5.0%, Cr: not less than 0.1% nor more than 10%, and the like, and a balance composed of Fe and inevitable impurities. To the molten steel, REM: not less than 0.0005% nor more than 0.03% is added. The molten steel to which REM has been added is casted. A cast slab of non-oriented electrical steel is manufactured as above.
