FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, namely to a sheet of non-textured electrical steel having a tensile strength of 600 MPa or more and used as a material for the manufacture of iron cores of engines or compressors. The steel sheet has the following composition, wt.%: 0<C≤0.0035, Si: 2.0 - 3.5, Mn: 0.4 - 1.2, P: 0.03 - 0.2, Al: 0.4 - 2.0, if necessary, at least one element of Sb and Sn with a total content of 0.003 - 0.2 and if necessary, at least one element of Mg, Ca and REM with a total content of 0.0005 - 0.01, the rest is Fe and unavoidable impurities. The sheet has a share of the texture of the plane {100} ≥ 25% and a share of the texture of the plane {111} ≤ 31%.

EFFECT: sheet has a high magnetic induction and low losses in iron.
