Zusammenfassung:	In viscosimetric experiments on 32Г1 and 32Г2 liquid steel from oil and gas pipe, the temperature dependence of the kinematic viscosity is determined. The viscosity is measured by means of damping torsional oscillations of a crucible with melt in heating and subsequent cooling within the range 1450–1810°C. The results are interpreted in terms of the microheterogeneous structure of the metallic melts. On that basis, recommendations are made regarding the optimal heat treatment of 32Г1 and 32Г2 liquid steel. For 32Г2 steel, it is expedient to increase the melt temperature to 1650–1670°C.
