Will Q345NH steel plate peel off after rust?

The main technical support point of the rust steel plate that can be used as a facade material is that the rust Q345NH steel plate has superior corrosion resistance compared with ordinary weather-resistant steel. In natural climates, the rust steel plate Q345NH forms a layer of about 50-100 microns thick between the rust layer and the substrate by adding chrome, niobium, molybdenum, nickel, titanium, rare earth and other weather-resistant alloy elements between the rust layer and the substrate. Oxide layer with good metal adhesion (ie rust red).

Corrosion resistance

Due to the existence of this dense oxide film, it prevents the penetration of oxygen and water in the atmosphere into the steel matrix, slowing down the development of rust into the steel material, thereby greatly improving the atmospheric corrosion resistance and decorative effect of the rust steel plate material. The research indicates that the corrosion resistance of the rust steel plate can be increased by 5-8 times than that of the ordinary weather-resistant steel due to the different composition of the rust steel plate and the different use environment of the steel components. Due to the special dense oxide layer that can be formed on the surface of the rust steel plate, it has a stable and uniform natural rust red, which makes it an attractive building exterior wall material and a revolutionary material for the new generation of curtain wall decoration. Q345NH steel is better cost-effective than stainless steel.

Real rust Q345NH steel plate: uniform rust red, good color fastness and solidity, no peeling, no slag, no rust water flowing in the later period, super corrosion resistance. Welcome to send email to [email protected] if you are interested in our Q345NH steel price.
