FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, namely to a sheet of anisotropic electrical steel used as a material for iron cores of transformers. A sheet of electrical steel contains a steel sheet substrate and an insulating coating with tension located on the surface of the steel sheet substrate. The sheet substrate has a ten-point average roughness RzL in the rolling direction of 6.0 microns or less.
EFFECT: sheet has a high magnetic induction and low magnetic losses.
