New vanadium-microalloyed reinforcement steels with improved weldability have been developed. The criteria that are used to evaluate a steel’s weldability based on its contents of carbon, manganese, silicon, and vanadium are analyzed. Results obtained from a regression analysis of the mechanical and service properties of the steels were used to construct nomograms for calculating and optimizing the chemical composition of vanadium-microalloyed reinforcement steels and 8–40-mm-thick rolled reinforcement bars with respect to their contents of carbon, manganese, and silicon.
