Q960E steel has the characteristics of high yield strength and high tensile strength, and it contains one or several alloying elements, with a low or moderate degree of alloying. The main function of alloying elements in Q960E steel is to improve the hardenability of steel and ensure the expected comprehensive properties of parts after tempering at high temperature.
