Nonoriented electrical steels are silicon aastm in which magnetic properties are practically the same in any direction of magnetism in the plane of the material.

The values given in parentheses are mathematical conversions to customary cgs-emu and inch-pound units which are provided for information only and are not considered standard.

In addition, cold finishing plus strip annealing produce a aatm surface and reduce buckles and waves, resulting in excellent flatness and a high stacking factor.

For surface insulation, the electrical steels shall be supplied with a smooth surface finish and a thin, tightly adherent surface oxide, or applied coatings if needed.

Desirable core-loss and permeability astj are developed during mill processing, so additional heat treatment is usually not necessary.
