Three reasons for oxidation of stainless steel

1. Reasons for the production process: This is one of the reasons for the oxidation of steel products. From the perspective of the production process and product characteristics, forming a thin oxide film on the surface of the product is the basic process to prevent oxidation. It is also a steel product. One of the main characteristics that are different from other steel products, but when the oxide film is incomplete or discontinuous due to the lack or neglect of the production process, the oxygen in the air directly reacts with some elements in the product to oxidize and restore, which leads to The product exhibits oxidation.

2. Reasons for the proportion of product components: In order to reduce consumption costs, some manufacturers reduce the proportion of important elements such as chromium and nickel, while increasing the content of other elements such as carbon. This does not strictly follow the product model and product characteristics. To stop the consumption phenomenon of component ratio, not only the production quality is greatly reduced. For example, when the chromium content of 304 stainless steel pipe is lacking, it not only affects the corrosion resistance and formability of the product, but also when used in the chemical, equipment, and consumer industries. There is a potential safety hazard in production and quality; at the same time, it also affects the appearance and antioxidant properties of the product.

3. Human reasons: This is also one of the most common reasons for product oxidation that some consumers encounter when using stainless steel products. Some consumers improperly operate and maintain products, especially some stainless steel pipe products used in the food and chemical equipment industry. There is a high probability of man-made oxidation. Regarding man-made oxidation of steel products, it is necessary to have the correct product application knowledge and regularly stop reasonable and effective maintenance and care, so as to reduce the oxidation caused by improper use.
