Non-oriented electrical engineering steel plates

Abstract

The term refers to the impregnation of non-oriented electrical steel with a chemical composition in which α-γ transformation may occur and containing at least, by mass percentage, 0.010% or more of c, 1.50% to 4.00% Sì, and 0.0001% to 1.0% sol. Al, 0.010% or less; S, 0.010% or less; N, and a total of 2.50% to 5.00% of at least one element selected from the group of elements including Mn, Ni and Cu, with the remainder consisting of Fe and impurities, where the average grain size of the crystal {411} is determined to be (1411 and the average grain size of the crystal {111} is determined to be di11, chi 1 / di II ^1,10,
