FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy. To provide electrical insulation of the base metal material and imparting chemical and thermal resistance to it, a sheet article of electrical steel with an oriented structure comprises an insulating coating layer applied on at least one surface of said sheet article, wherein said insulating coating comprises a matrix containing phosphate and silicon dioxide. In addition, the insulation contains particles of filler, wherein said particles of filler contain core consisting of material with high Young's modulus, and shell, at that shell encloses said core and consists of material, by means of which particles of filler are connected with matrix.
EFFECT: eliminating the need to add chromium compounds to an insulating coating of an article of sheet steel with an oriented structure.
