Weathering steel is an ornamental steel. What are the unique features of weathering steel? Let's learn about it from the weathering steel manufacturer.
The main technical support for the use of weathering steel as a facade material is that weathering steel has a strong corrosion resistance compared with ordinary steel. Under natural weather conditions, weathering steel forms a dense oxide layer of about 50-100 microns thick and good adhesion to the base metal between the rust layer and the substrate by adding weathering elements such as chromium, niobium, molybdenum, phosphorus, and titanium.
Because of the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from penetrating into the steel substrate, slowing down the development of rust into the depth of the steel material, thereby greatly improving the steel material's resistance to atmospheric erosion. Studies have shown that depending on the composition of weathering steel and the use environment of steel components, the atmospheric erosion resistance of weathering steel can be 5-8 times higher than that of ordinary steel.
