09CuPCrNi-A weathering steel plate is smelted by adding a small amount of copper, nickel and other weathering elements into ordinary carbon steel, which has certain weathering performance in practical application. Therefore, it has a wide range of applications in many buildings and bridges. 09CuPCrNi-A weathering steel plate is not stainless steel plate, it will also produce corrosion after contacting with the atmosphere. In order to increase the understanding of 09CuPCrNi-A weathering steel plate, let's learn about the rust What are the characteristics of 09CuPCrNi-A weathering steel plate.

The rust layer of 09CuPCrNi-A weathering steel plate is the oxide of a variety of alloy elements, which is reddish brown. The rust layer is very dense, which prevents the further corrosion of 09CuPCrNi-A weathering steel plate, which is characterized by weather resistance and non-corrosion. However, the formation of this layer of rust in natural conditions takes a long time, so generally, artificial means will be taken to promote the formation of rust layer. The rusty steel plate with a complete reddish brown layer is often used as a landscape, which is very beautiful. The corrosion of 09CuPCrNi-A weathering steel plate in natural climate makes the steel material form a dense oxide layer between the rust layer and the substrate. Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, so as to improve the atmospheric corrosion resistance of 09CuPCrNi-A weathering steel plate.

After contacting with the atmosphere, the 09CuPCrNi-A weathering steel plate forms a layer of dense oxide film on the steel surface, which is closely attached to the steel base, so as to prevent the further corrosion of the atmosphere and the base, and play a certain role in protecting the steel base. The corrosion of this layer will gradually change into different colors over time.
