Anotation

This specification deals with flat-rolled electrical steels for magnetic applications. These steels are composed principally of iron with relatively small amounts of alloying elements such as silicon and aluminum. The magnetic properties of the material shall be specified. Electrical steels are normally provided with an electrical resistivity appropriate to the core-loss limit and the specified end use. The surface insulation ability may differ widely with the class of electrical steel and the intended end use. Several types of applied coatings available to attain different levels of insulation ability are: C-0, C-2, C-3, C-4, C-4AS, C-5, C5-AS, and C-6. Mechanical properties such as ductility, lamination factor, tensile or yield strength, and so forth shall be specified. Magnetic, electrical, and mechanical tests shall be made.
