Weathering steel, as a new generation of advanced steel material, has an atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel, and the longer the service time, the more prominent the corrosion resistance. Due to its rust resistance, coating-free, thinning and consumption reduction, labor-saving and energy-saving features, Q355GNH steel can be applied to steel structures that are exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, and towers. It can also be used to make containers, Structural parts such as railway vehicles, oil derricks, seaport buildings, and oil production platforms.
Q355GN weathering steel is characterized by adding a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to the steel to form a dense layer between the stainless layer and the substrate, which prevents oxygen and water in the atmosphere from penetrating into the steel substrate and slows down Corrosion develops in depth to steel materials, which greatly improves the atmospheric corrosion resistance of steel materials. Among them, Q355GN weathering steel has been widely used in the manufacture of 70t and 80t trucks.
