    Building Steel Structure High Strength Steel Plate Q690D Q690E


    Q690D high strength low alloy steel is a high strength welded structural steel, where "Q" stands for yield strength, "690" stands for yield strength value, and "D" stands for grade.


    Q690D low alloy steel material has good welding performance and fatigue resistance, and Q690D low alloy structural steel is easy to cut, bend and other processing operations.


    Q690D low alloy steel sheet can be widely used in coal mining machinery, engineering machinery, such as hydraulic supports, port cranes, and flatbed transporters.


    ‌Q690E alloy steel plate is a high-strength welded structural steel. "Q" stands for yield strength, "690" means the minimum yield strength is 690MPa, "E" stands for quality grade, and the impact test temperature is -40°C.


    ‌‌Q690E low alloy steel material performance characteristics‌

    High toughness‌: ‌Q690E low alloy steel sheet can still maintain good ductility at low temperatures.
    ‌Good welding performance‌: The welded joint is of high quality and not prone to cracks.
    ‌Wear resistance and corrosion resistance‌: ‌Q690E high strength low alloy steel plate surface is specially treated to improve wear resistance and corrosion resistance.
