Introduction To The Classification Of Weather-resistant Steel Plates

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 steel's resistance to atmospheric corrosion. A small amount of molybdenum, niobium, Vanadium, titanium, zirconium and other elements are used to refine the grains, improve the mechanical properties of steel, improve the strength and toughness of steel, reduce the brittle transition temperature, and make it have better resistance to brittle fracture.
Weathering steel for welded structures
The elements added to the steel type, except for phosphorus, are basically the same as high weather-resistant structural steel, and their functions are also the same, and improve the welding performance.
