Chemical elements in 05CuPCrNi weather resistance steel plate

The core of 05CuPCrNi weather resistance steel plate design is to ensure its resistance to atmospheric and seawater corrosion. BBN is a well-known supplier and exporter of 05CuPCrNi weather resistance steel plate in China. The quality of 05CuPCrNi weather resistance steel plate depends on the chemical elements in the steel sheet.

Among them, copper is the most important element for the 05CuPCrNi weather resistance steel plate, and nickel has little effect on the weather resistance of steel plates. In 05CuPCrNi weather resistance steel plate, copper is an active cathode. The copper precipitated on the surface of the copper-containing steel plate can promote the anodic passivation of the 05CuPCrNi weather resistance steel plate, form a dense, good adhesion rust layer, and reduce the corrosion rate of the substrate in the external medium.

The addition of P element is beneficial to improve the corrosion resistance of the 05CuPCrNi weather resistance steel plate. Phosphorus is an anode depolarizing agent, which can promote the uniform dissolution and corrosion of 05CuPCrNi weather resistance steel plate, increase the polarization resistance of the rust layer on the surface of the steel substrate, and slow the entry of corrosive media into 05CuPCrNi weather resistance steel plate.
