FIELD: metallurgy.
SUBSTANCE: invention relates to sheet from textured electrical steel. Described is a sheet from textured electrical steel having a coating on its surface, wherein the coating has a complex modulus of elasticity of 60 to 95 GPa and a film thickness of 1.0 mcm or more and 3.5 mcm or less, and the tension created by the coating on the textured electrical steel sheet is 6.0 MPa or more and 18.0 MPa or less, and the coating is obtained from a solution containing at least one phosphate selected from phosphates Mg, Al, Ca and Sr, and contains 50–150 pts. wt. of colloidal silicon dioxide in terms of content of solid substance per 100 pts. wt of phosphate, and value of deterioration of losses in iron W17/50 in the period before and after reduction by rollers, when sheet from textured electrical steel is subjected to reduction by rollers with linear pressure of 68.6 N/cm, is 0.010 W/kg or less.
EFFECT: suppressing deterioration of magnetic properties.
