The structural state and mechanical properties of cold-rolled steel of strength class 340 MPa or grade HC340LA of the current production, annealed in bell-type furnaces, were examined on the metals of eight industrial melts. The results demonstrate the expediencies of using an economical alloying and microalloying system and optimizing the technologies for smelting, hot and cold rolling, and recrystallization annealing of steel.
