用于电机磁芯的无晶粒取向（NO）电工钢等级的片材应在整个片材平面内具有均匀的磁性。引入了基本的经验模型来估计和关联磁性能与材料的微观结构参数。在这些考虑中，钢板通常被认为是均匀的，也就是说，方向依赖和钢板厚度的变化往往被忽略。无论这些简化是否合理，如何描述晶粒尺寸和织构最适合与磁性能的相关性是本文讨论四种工业NO钢牌号的重点。
Laminations of non-grain-oriented (NO) electrical steel grades for magnetic cores of electrical machines should feature homogenous magnetic properties within the entire sheet plane. Basic empirical models have been introduced to estimate and correlate magnetic properties with microstructural material parameters. In these considerations, the steel sheets are generally considered to be homogenous, i.e., orientation dependence and variations across the sheet thickness are often disregarded. Whether or not, these simplifications are justified and how grain size and texture are described most suitable for correlations with magnetic properties is the focus of this paper discussing four industrial NO steel grades.
