In the paper, the properties, microstructure, cost and yield of low-alloy high-strength hot-rolled H-beam with niobium vanadium and titanium microalloying by industrial production are compared on the premise of satisfying the technical indexes of product as well as they are analyzed and discussed in detail combining with the theories. The hot rolled H-beam with such three components as niobium, vanadium and titanium has advantages and disadvantages so that the microalloy system can be selected for production according to the actual situation of enterprise and market price of alloys.
