Introducing Jigang vanadium nitrogen alloy micro-alloying process HRB400 steel production situation. The effect of micro-alloying of vanadium and nitrogen on the microstructure and properties of the steel bars was studied. The relationship between the chemical composition and mechanical properties of the micro-alloying of vanadium and nitrogen was analyzed. The results show that the use of vanadium nitrogen alloy HRB400 steel production process is feasible.
