Grain Oriented Electrical Steel Sheet

Abstract: In this grain-oriented electrical steel sheet, the average value avefL of an angle deviation f determined at a plurality of measurement points at 1 mm intervals along the rolling direction L is 3.5° or less; particle sizes DL10 representing 10% of particle sizes DL determined along the rolling direction L, which have been arranged in descending order, in terms of the count from large to small are (100–15×avefL) mm or less; and the average value aveDC of particle sizes DC determined along a direction C orthogonal to the rolling direction is 50 mm or more.
