This report presents the results of a study of laboratory-produced hot-rolled low-carbon steels microalloyed with niobium, titanium, vanadium, and molybdenum in various combinations and concentrations. An analysis was made of the influence of the hot rolling finishing parameters, the microalloying system, and the structural state, including nanosized phase precipitates of various types, on mechanical properties of the rolled products. The results showed that various combinations of the final hot rolling stage modes and the microalloying system lead to the implementation of different strengthening mechanisms.
