Effect of Boron on Microstructure and Mechanical Property of High Grade Pipeline Steel

Abstract:

The correlation among boron, microstructure and mechanical property of the X120 pipeline steel was investigated in this study. The mechanical properties of the steels were tested with quasi-static tensile testing machine. The microstructure of the steels with different boron contents was observed with scanning electronic microscope (SEM) and transmission electronic microscope (TEM). The result shows that by adding a small amount of boron the mechanical property of pipeline steel can be improved effectively.
