The high performance Q345E steel with high yield strength and stable low-temperature impact toughness was made by Titanium microalloying technology.The microstructure of developed Q345E steel is composed of ferrite, pearlite and a little tempered sorbite.Slow cooling and fast cooling experimental results showed that titanium microalloyed Q345E steel has high performance stability, the increase of strength is caused mainly by grain-refining strengthening and precipitation strengthening.This research is a beneficial attempt for further promotion of titanium microalloyed steel.
