Common corrosion types and causes of Q355NH high-speed project steel

The secondary quenching and low temperature tempering of Q355NH high-speed project steel, wear-resistant composite plate is mainly used for important carburized parts with high mechanical properties, especially for coarse grain steel. However, after carburizing, it needs to be heated twice at high temperature to increase the deformation and oxidation decarburization of the workpiece.

Q355NH high-speed project steel, Wear-resistant steel plate has good corrosion resistance:
The alloy layer of the wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has certain anti-rust and corrosion resistance. It can be used to prevent coal sticking when it is used in coal dropping drums and hoppers.
