What are the classifications of weather resistant steel plate

Add a small amount of copper, phosphorus, chromium, and nickel to the steel grades of high weather resistance structural steel to form a protective layer on the surface of the metal collective to improve the performance of atmospheric corrosion resistant steel. You can also add a small amount of molybdenum, niobium, vanadium, titanium, Elements such as zirconium refine grains. Improve the mechanical properties of weather resistant steel plate, increase the strength and toughness of weather resistant steel plate, reduce the ductile-brittle transition temperature, so that it has better resistance to brittle fracture and resistance.

The welded structure uses weather resistant steel plate, and the added elements of the steel grade are basically the same as high weathering structural steel except for phosphorus, and have the same function. And improve the weldability of structural steel with high weather resistance, because the performance of atmospheric corrosion resistance is better than that of structural steel. Weather resistant steel plateis mainly used for bolting and riveting of structures and structural parts such as vehicles, containers, buildings, and towers.

When making welding and structural parts, the thickness of the steel must not exceed 16 mm. Structure, weather resistant steel plate used for welding has better weldability than structural steel and has high weather resistance. Weather resistant steel plate is mainly used in bridges, buildings and other welded structural parts.
