Q550D low alloy steel plates Products Details
The chemical composition of Q550D high strength low alloy structural steel plate is carefully blended to achieve its unique properties. The content of major elements such as carbon, silicon and manganese, as well as the addition of alloying elements such as copper, chromium, nickel, molybdenum, boron, vanadium, niobium and titanium, all provide Q550D high strength low alloy steel plates with excellent mechanical properties. Its yield strength and tensile strength are as high as 500-600MPa, and its elongation and section shrinkage are also quite high, 18%-25% respectively. Together, these features give Q550D high strength low alloy steel sheet excellent impact resistance and fatigue resistance, enabling it to maintain stable and reliable performance in a variety of complex environments and loads.
