Effect of Finish Rolling Temperature on Microstructure and Mechanical Properties of High Grade Pipeline Steel

摘要：

The correlation among finish rolling temperature (FRT), microstructure and mechanical property of the high grade pipeline steel was investigated in this study. The microstructure of the steels with different finish rolling temperatures was observed with scanning electronic microscope (SEM) and transmission electronic microscope (TEM). The martensite/austenite (M/A) islands distribution was fixed by colour metallography, and the mechanical properties of the steels were tested with quasi-static tensile testing machine. The result shows that the fraction of M/A island increased with the finish rolling temperature decreasing, and when the finish rolling temperature is 800℃, the mechanical properties are the best.
