The weathering steel, namely atmospheric corrosion-resistant steel, is a low-alloy steel between ordinary steel and stainless steel. The weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It makes the steel material form a dense oxide layer between the rust layer and the matrix, prevents the infiltration of oxygen and water in the atmosphere into the steel matrix, and slows down the in-depth development of corrosion to the steel material, so as to improve the atmospheric corrosion resistance. The atmospheric corrosion resistance is 2-5 times that of ordinary carbon steel. It has the characteristics of toughness, plastic extension, forming, welding and cutting, corrosion, high temperature and fatigue resistance of high-quality steel.
