Weather-resistant structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. According to its main characteristics, it is divided into high-weather-resistant structural steel and weather-resistant steel for welded structures.
high weathering steel
High weather resistance structural steel is to add a small amount of copper, phosphorus, chromium and nickel elements to the steel to form a protective layer on the collective surface of the metal to improve the atmospheric corrosion resistance of the steel. A small amount of molybdenum, niobium, Vanadium, titanium, zirconium and other elements to refine the grain, improve the mechanical properties of steel, improve the strength and toughness of steel, reduce the brittle transition temperature, so that it has better resistance to brittle fracture.
Weathering steel for welded structures
The elements added to the steel, except for phosphorus, are basically the same as the high weather resistance structural steel, and its effect is the same as that of it, and improves the welding performance.
