V and Ti-V microalloyed steels were produced in Chenggang 1780 hot rolling line.The effect of micro-Ti treatment on microstructure and mechanical properties of vanadium microalloyed steels has been studied in this paper.The experimental results demonstrate that a little amount of TiN precipitation can be obtained after micro-Ti treatment and its quantity is less,can not effectively refine ferrite grains in V microalloyed steels;the amount of precipitation of vanadium reduced because of the priority of titanium and nitrogen combined,then tensile and yield strength values of vanadium microalloyed steels can decrease about 54 MPa,45 MPa respectively,and the elongation was up slightly.
