Stainless steel wire filter cartridge is black after using for a period of time. What causes it? The first thing is to look at the chemical composition of the stainless steel filter cartridge. The three main elements of stainless steel are iron, nickel, and chromium. The three metals are produced in different shares. The produced stainless steel wire products also have different functions. If the content of iron in the three elements does not change, the higher the chromium content, the brighter the stainless steel wire, and the higher the nickel content, the darker the stainless steel wire. If the content of chromium and nickel is not
changed and the content of iron is increased, the stainless steel wire will be darkened. This is mainly based on the initial appearance of the product.
If we get black when we use it, it must be cause
d byoxidation. Products containing iron can quickly turn black when heated. The master does not necessarily show signs of rust. In other cases, the smoothness of the wire drawing machine during the production process is not good enough. The frictional resistance is relatively large. The severe external heating in the stainless steel filter cartridge will cause the segregation of the metal elements inside the steel wire, the alloy composition will be dissected out, and then the appearance will become black.
It can be understood from the situation above that the reason for the blackening of the stainless steel filter cartridge is not single. The above is the problem of blackening of stainless steel filter cartridges. I hope to help you understand stainless steel products.
