In order to take the most appropriate method, you must first understand the three major causes of oxidative corrosion of
stainless steel coils.
The first is the production process, which is one of the important reasons for oxidation and rust of stainless steel coil products. From the production process and product characteristics, the formation of a thin and dense oxide film on the surface of stainless steel coil products is to prevent the formation of oxidation. Basic technology is also one of the main features that distinguish stainless steel coil products from other steel products. Therefore, when the oxide film is incomplete and discontinuous due to insufficient production technology or negligence, the oxygen in the air will directly interact with the product. Some elements produce redox reactions, causing oxidation of stainless steel coil products.
The second reason is the ratio of product ingredients. In order to reduce production costs, some steel mills reduce the proportion of some important elements such as chromium and nickel, while increasing the content of other elements such as carbon. This does not strictly follow the product The production situation of the ingredient ratio based on the model and product characteristics will not only greatly reduce the quality of the stainless steel coil products, for example, when the chromium content of the 304 stainless steel pipe is insufficient, it will not only affect the corrosion resistance and formability of the product, but also be used in In the chemical, equipment, and production industries, there will be potential product quality and safety hazards, and it will also damage the appearance and antioxidant properties of stainless steel coil products.
The third is human reason, which is also one of the most common causes of product oxidation encountered by some consumers when using stainless steel coil products. Some consumers operate improperly in the use and maintenance of stainless steel coil products, especially those used in food and chemical equipment. The stainless steel pipe products in the industry have a high probability of artificial oxidation. For the artificial oxidation of stainless steel products, it is necessary to have correct product usage knowledge and perform reasonable and effective maintenance on a regular basis, so as to reduce the human-induced oxidation caused by improper use. oxidation phenomenon.
