Stainless steel often has three major causes of oxidation

1.Reasons for consumption process: This is one of the reasons for the oxidation of steel products. From the perspective of consumption technology and product characteristics, forming a thin oxide film on the surface of the product is a root-end process that prevents seizure oxidation, and is also a steel product. Different from one of the main characteristics of other steel products, but when the consumption process is lacking or neglected and the performance of the oxide film is not perfect or discontinuous, the oxygen in the air directly reacts with some elements in the product to oxidize and recover, thus causing The product exhibits an oxidative phenomenon.
2.the proportion of product ingredients ratio: some manufacturers in order to reduce the cost of consumption, thereby reducing the proportion of some important elements such as chromium, nickel, and other content such as carbon, such as not strictly according to product model, product characteristics To stop the consumption of ingredients, not only the quality of production is greatly reduced. For example, when the content of chromium in 304 stainless steel tube is lacking, it not only affects the corrosion resistance and formability of the product, but also is used in chemical, equipment and consumer industries. There are potential safety hazards of production quality; at the same time, it also affects the appearance and oxidation resistance of the product.
3. human reasons: This is one of the most common reasons for some customers in the use of stainless steel products, some consumers in the application and maintenance of improper use, especially for the stainless steel pipe products used in the food chemical equipment industry The probability of artificial oxidation is high. Regarding the oxidation phenomenon of artificial steel products, it is necessary to have correct product application knowledge and regular maintenance and maintenance of reasonable stop, thus reducing the oxidation phenomenon caused by improper application.p201701061714040039041
