GB/T1591 Q460D HSLA structural steel plates steel plate

GB/T1591 Q460D HSLA structural steel plates have good fatigue resistance and low temperature toughness, as well as good cold forming and welding performance. Q460D steel plates mainly adapt to the production of high strength engineering machinery, transportation machinery, construction machinery, machinery machinery, coal mine hydraulic support, crane arm leg, frame, steel structures and so on, especially low temperature and high strength structural parts.

GB/T1591 Q460D HSLA structural steel plates chemical composition and mechanical property:

Grade C % Si % Mn  P % S %  
Q460D ≤0.20 ≤0.55 1.00-1.70 ≤0.030 ≤0.030  
Grade Thickness Yield Strength (Mpa) Tensile Strength Elongation(%) Impact Energy
(mm) (MPa) Min 
Q460D ≤16 460 550-720 17 -20 34
>16-35 440 550-720 17 -20 34
>35 420 550-720 17 -20 34
The min impact energy is longitudinal energy

BBN steel not only supply GB/T1591 Q460D HSLA structural steel plates, but also provide processing, such as cutting, welding, drilling, bending, etc. For any demands or information of Q460D steel plates, welcome to communicate with BBN steel freely.
