The manufacturing process of Q500NH corten steel sheet

With our bar bending experience and expertise—along with proper tooling, methods, and machinery—we can bend relatively thin and wide bars to tight radii with little to no distortion. We can bend a wide variety of bars, including hot rolled carbon steel, stainless, alloy, Inconel, brass, copper, and other alloys.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, Q500NH corten steel sheet, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

Temperature has a great influence on the strength of the material, Q500NH corten steel sheet. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

As we are supplying EN 10028-3 Grade P355NH fine grained structure steel plates and Q500NH corten steel sheet in China since 2008 to many petrochemical companies and in energy sector industries. We have become a preferred hot-rolled plates supplier in China.
