EFFECT OF VANADIUM ADDITION ON API X100 LINEPIPE STEEL

摘要：

　　This study is focused on the effect of vanadium addition to an API X100 steel.Laboratory heats were melted and control rolled based on a coil plate production process.Compared to non vanadium steel,it was found that 0.06%vanadium added steel had 8 to 14%higher yield and tensile strengths in all directions,while the toughness and ductility were similar for both steels.It is believed that the higher strength of the vanadium steel was partially due to its smaller grain size,larger fraction of sub grain boundaries and a higher number of uniformly distributed carbonitride precipitates in the vanadium steel.
