Q690D HSLA Steel Sheet
Q690D low alloy steel plate belongs to high strength welded structural steel. Where Q stands for yield strength, 690 stands for yield strength value and D stands for the grade of the steel plate.
Q690D low alloy structural steel higher yield strength and tensile strength, widely used in coal mining machinery, engineering machinery, such as hydraulic support, harbour crane, flatbed truck.
