Q355GNH corrosion-resistant steel is a steel that adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the surface of the metal substrate to improve the resistance to atmospheric corrosion.

Q355GNH corrosion-resistant steel has the properties of high-quality steel such as toughness, ductility, forming, welding, abrasion, high temperature, fatigue resistance, etc. At the same time, it has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving.
