Weathering steel, that is, atmospheric corrosion resistant steel, is a series of low alloy steel between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion resistant elements such as copper and nickel. It has the strength, ductility, forming, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics of high-quality steel; The weathering resistance is 2~8 times of that of ordinary carbon steel, and the coating resistance is 1.5~10 times of that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance and life extension of components, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaic, high-speed projects, etc. It is used to manufacture structural components such as containers, railway vehicles, oil derricks, harbor buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
It is characterized by: the alloy composition and weight percentage content of weathering steel are: C: ≤ 0.12, Si: 0.25~0.75, Mn: 0.2~0.5, S ≤ 0.02, P: 0.06~0.12, Cu: 0.25~0.5, Cr: 0.3~1.25, Ni: 0.12~0.65, and the rest are Fe and trace elements.
Through the alloying of Cu, Mn, Si, Al and other elements, and simply adjusting the content of some elements in ordinary low carbon steel (Q235 steel), the economic weathering steel with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel.
