Corten steel plate, also known as corrosion-resistant steel, Corten steel, also known as atmospheric corrosion-resistant steel, originated from Corten steel in North America. It is a low-alloy steel series between ordinary steel and stainless steel. It has the characteristics of easy ductility and high resistance of ordinary steel. Strength, fatigue resistance and other properties, while the corrosion resistance is 2-8 times that of ordinary steel.
Weathering principle: A certain amount of copper, as well as corrosion-resistant elements such as phosphorus, chromium, nickel, titanium, and vanadium are added to plain carbon steel to form a dense and highly adherent oxide layer between the rust layer and the matrix. , this special dense oxide layer has stable and uniform natural rust-red characteristics, which can prevent oxygen and water in the atmosphere from penetrating into the substrate, protect the substrate under the rust layer, and slow down its corrosion rate.
It is this dense layer of rust that prevents the weathering steel from continuing to corrode even though it is rusted on the surface.
