Effect of Microalloying Elements on the Microstructure and Elevated-Temperature Mechanical Behavior of High-Strength Drill Pipe Steel

The mechanical behavior of S135 and V150 (Mo-V-Nb microalloyed) drill pipe steels was systematically investigated at room temperature (RT) and elevated temperatures (100–300 °C), alongside the microstructural evolution after long-term thermal exposure at 310 °C (200–500 h). V150 steel exhibits a superior RT yield stren...
