Corrosion steel plates are low alloy structural steels with a protective antirust layer to resist atmospheric corrosion and are used in the manufacture of steel structures such as vehicles, bridges, towers and containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared to stainless steel, weathering steels contain only small amounts of alloying elements such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium and titanium. Unlike stainless steel, the total amount of alloying elements is only a few percent of steel, up to 100 percent. Ten percent, so the price is relatively low.
Atmospheric steel, that is, atmospheric corrosion-resistant steel, is between ordinary steel and stainless steel series of low alloy steel. Weathering steel is made from ordinary carbon steel with small amounts of corrosion-resistant elements (such as copper and nickel). It has the toughness and plasticity of a high quality steel. Extension, molding, welding and cutting, wear resistance, high temperature resistance, fatigue resistance, etc.; weatherability is 2-8 times that of ordinary carbon steel, coating performance is 1.5-10 times that of ordinary carbon steel. At the same time, it has the characteristics of anti-rust, corrosion resistance, long life of parts, thinning and consumption reduction, labor and power saving.
Atmospheric corrosion resistant steel is mainly used for steel structures that are exposed to the atmosphere for long periods of time, such as railroads, vehicles, bridges and towers. It is used in the manufacture of structural parts such as containers, railroad vehicles, derricks, harbor buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
