A709Gr50 high strength low alloy steel plate American Standard steel for bridges, also known as low alloy plate. Widely used in engineering structure.
A709Gr36 composition characteristics:
(1) Low carbon: Due to the high requirements of toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%.
(2) Addition of manganese-based alloying elements.
(3) adding niobium, titanium or vanadium and other co-elements: a small amount of niobium, titanium or vanadium in the steel to form a fine carbide or carbon-nitride, which is conducive to obtaining a fine ferrite grain and improve the strength and toughness of steel.
In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (0.1% or so), etc., can improve corrosion resistance. Add a small amount of rare earth elements, can be desulfurized, de-gassing, so that the steel purification, improve toughness and process performance.
