FIELD: metallurgy.
SUBSTANCE: invention is a sheet of non-oriented electrical steel used as a material for the manufacture of iron cores of traction motors for electric vehicles. The sheet of non-oriented electrical steel includes the following chemical elements, % by weight: 0< C≤ 0.005 Si: 2.0-3.5 Mn: 0.1-2.0, at least one element of Sn and Sb: 0.003-0.2 Al: 0.2-1.8, the rest are Fe and inevitable impurities, while the specified sheet contains inclusions of MnS and Cu2S with a size of 150-500 nm.
EFFECT: low iron loss and low magnetic anisotropy at high frequencies.
