The specially designed alloying element distribution in 05CuPCrNi weathering steel provides a protective layer, which in turn produces a corrosion inhibition effect. The protective layer on the surface of 05CuPCrNi weathering steel will slowly grow and regenerate with the influence of weather and climate. In short, the 05CuPCrNi steel plate is formed by the surface to produce a protective layer.
05CuPCrNi weathering steel is not stainless steel. It will rust like early carbon steel, but it will be different in the later stages. After a period of corrosion of 05CuPCrNi weathering steel, the surface of the weathered steel is enriched with trace elements such as Cu and P, forming a dense amorphous rust layer structure, and the 05CuPCrNi weathering steel matrix is very firmly bonded. This stable rust layer can resist the intrusion of water and harmful ions in the atmosphere to a certain extent and prevent further corrosion of the 05CuPCrNi weathering steel matrix metal.
05CuPCrNi steel can be exposed directly to the atmosphere without painting, After years, the rust layer gradually stabilizes, corrosion no longer develops, appearance is beautiful chocolate color. 05CuPCrNi bond has no problems such as paint ageing, no painting maintenance, greatly reduces the maintenance cost, of course, it also avoids the loss caused by the influence of painting on the 05CuPCrNi steel use and so on.
