Abstract：Research and production of lowcost VN microalloyed rebars with high strength have been reviewed. Enhancednitrogen in Vcontaining rebars promotes precipitation of fine V(CN) particles, and improves markedly precipitation strengthening effectiveness of vanadium. Industrial production results show that, V content in VN microalloyed rebars of 400 MPa level can be as low as 003%~004%, which has been reduced by about 50 percent and accordingly drive alloy cost cut down by a large degree. Accelerated cooling process optimizes size distribution of V(CN) particles in VN rebars and get further low V content.
