Conclusions
The existence of general rules governing changes in the hot plasticity, the similar values of resistance to deformation at corresponding temperatures and deformation rates of steel St3 austenitized at 1150°C and not austenitized, and the similarity in the formation of structure at tdef>850°C leads to the assumption that not deformation of similar steels is possible without preliminary high-temperature heating (1150–1200°C) during treatment by such methods as high-temperature thermomechanical treatment or controlled rolling.
