The method of trial production of high-strength microalloying 20 MnSi reinforced bar had been present in this paper. The mechanical properties and microstructures of the tested steel were investigated by universal tensile machine,scanning electron microscopy and transmission electron microscope. It was found out that the yield strength,tensile strength,elongation and yield ratio were 831 MPa,1 140 MPa,29.1% and 0.79,respectively,for the steel with 0.04%N and 0.047%V. It is expected that the improvement in mechanical properties of tested steel is attributed to the vanadium and titanium carbonitride precipitation strengthening.
