Non-oriented electrical steel plate

Abstract

The patent refers to non-oriented electroplating steel with a chemical composition capable of causing α-γ transformation, in which case the proportion of the area of ​​the oriented crystalline particles {hkl}<uvw> (within a tolerance of 10°·) when measured as EBSD is expressed as Ahkl-uvw, A4 i 1-011 is 15.0% or more, and the non-oriented electroplating steel has an average grain size from 10.0μm / η to 40.0μm.
