Weathering Corten Steel Plate For Sale

What is Weathering Corten Steel Plate?

Weathering corten steel, namely atmospheric corrosion-resistant steel, belongs to low-alloy high-strength structural steel. 

According to its main characteristics, it is divided into high weathering steel and weathering steel for welded structure

This photo shows a building made of Weathering Corten Steel. You can see that the surface looks like a layer of rust, which is actually protective oxide layer with superior corrosion resistance.

High weathering steel

High weather resistant structural steel is to add a small amount of copper, phosphorus, chromium and nickel to the steel to form a protective layer on the metal collective surface to improve the atmospheric corrosion resistance of the steel. It can also add a small amount of molybdenum, niobium, vanadium, titanium, zirconium and other elements to refine the grain, improve the mechanical properties of the steel, improve the strength and toughness of the steel and reduce the brittle transition temperature, It has good brittle fracture resistance.

Weathering steel for welded structures

In addition to phosphorus, the elements added to the steel are basically the same as those of high weather resistant structural steel, and their functions are the same, and the welding properties are improved.

Use of Weathering Corten Steel Plate

High weather resistant structural steel is mainly used for bolted, riveted and welded structural parts for vehicles, containers, buildings, towers and other structures because its atmospheric corrosion resistance is better than that for welded structures. When used as welded structural members, the thickness of steel shall not be greater than 16mm. The welding performance of weather resistant steel for welded structure is better than that of high weather resistant structural steel. It is mainly used for welded structural parts for bridges, buildings and other structures.
