As an important indicator of quality, each country divides the grade by the iron loss value. The lower the iron loss, the higher the grade and the higher the quality.B. High magnetic induction strength. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained. The volume and weight of the iron core of the motor or transformer made by it are relatively small, which can save silicon steel sheet, copper wire and insulating materials, etc.C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the iron core.D. Good punching property. This is more important for manufacturing small and micro motor iron cores.E. The surface has good adhesion and weldability to the insulating film.

电工钢硅钢片单取向电工钢指Goss取向，双取向特指立方取向电工钢。后者制备工艺极为复杂，目前难以工业化，所以取向硅钢广泛意义上指Goss取向。取向硅钢在易磁化的方向上具有高磁导率与低损耗特性，符合变压器等静态电力装备的导磁能力要求。单取向硅钢根据抑制剂和磁感的不同又可以分为CGO钢和Hi-B钢，具体如表1所示。其中，CGO钢的晶粒平均取向偏离角约为7°，饱和磁感值B8在1.82Tesla以上，主要用于中小型变压器的制造。Hi-B钢的晶粒平均取向偏离角约为3°，B8值在1.90Tesla以上，主要用于电力工业中的各种大型变压器、广东同城扼流圈等高端电磁元件的制造。
