In order to improve the performances of low-alloy high-strength hot rolled H beam product of Baotou Steel, reduce its production costs, enhance its product competitiveness as well as improve the economic benefits and production efficiency of enterprise, its characteristics such as the production technology, microstructure and performance are analyzed in this paper. The cost of alloy in steel is reduced and product profit is increased through the design idea of replacing vanadium with niobium and reducing Mn so that its mechanical properties are ensured to meet product standards.
