High-strength pipeline steels recently developed for severe regions are required to have high deformability as well as excellent low-temperature toughness and weldability to improve the fracture resistance to sudden deformation and fractures caused by heavy storms, earthquakes, and seismic sea waves. Since new design methodology so-called strain-based design was introduced in pipeline steels, therefore, many studies were are currently underway. In order to install pipeline at the severe region, the use of the pipeline steels with high deformability is perhaps most important. Because the high-strength pipeline steels contain complex microstructures dependent on the chemical composition and processing conditions, however, it is very difficult to characterize the microstructure classified according to the morphological features and to predict tensile properties associated with deformability. Accordingly, the present study aims to predict the tensile properties based on microstructural factors in various high-strength pipeline steels.
