High weatherability structural steel is to add a small amount of copper, phosphorus, chromium, nickel elements to the steel, so that it forms a protective layer on the collective surface of the metal, so as to improve the atmospheric corrosion resistance of the steel. A small amount of molybdenum, niobium, vanadium, titanium, zirconium and other elements can also be added to refine the grain, improve the mechanical properties of steel, improve the strength and toughness of steel, and reduce the brittle-transition temperature. So that it has better anti-brittleness and breaking performance.
With high quality steel toughness, plastic extension, forming, welding and cutting, corrosion, high temperature, fatigue resistance and other characteristics
