In this paper, it is shown that the “multiparameter” methods of magnetic structuroscopy that are based on the measurement of magnetic parameters, the accuracy of which is not high, can not provide reliable control of the structure of steels. Alternatively, parameters that are sensitive to structural changes in steels are proposed, for the formation of which the remanent magnetization Mr, the saturation magnetization Ms and the coercive force Нc on the saturation hysteresis loop can be measured. It is shown that the structural sensitivity of these parameters is higher, or no worse than the structural sensitivity of Нc, Mr, magnetic permeability and relaxation magnetic parameters, and they can be measured in a simpler way and more accurately.
