Products Description
Weather Resistant steel
It is between ordinary steel and stainless steel in the natural climate, weathering steel by adding niobium, molybdenum, phosphorus, titanium and other weathering elements make the steel material form a dense oxide layer between the rust layer and the substrate.
Weather steel plate, with alloy elements, such as Cu, Cr, Ni added, the anti-corrison structural steel acquires a corrosion resistance ability and extends the service life, in the development and producing of anti-corrosion structural steel. Our weather steel plates suitable for welding and bending, anti-corrosion structural steel is easy to use, and widely used in the field of marine container and railway industries. Atmospheric corrosion resistance is 2~5 times that of ordinary carbon steel.
