Why does 304 stainless steel seamless pipe oxidize?

1. Production process

This is one of the reasons for the oxidation of 304 stainless steel seamless pipes. From the production process and product characteristics, forming a thin oxide film on the surface of the product is the basic process to avoid oxidation, and it is also the difference between stainless steel and other steel products. One of the main features. However, when the oxidation film is incomplete and discontinuous due to insufficient production technology or negligence, the oxygen in the air directly reacts with some elements in the pipe, resulting in oxidation of the product.

2. Ingredient ratio
In order to reduce production costs, some manufacturers reduce the proportion of important elements such as chromium and nickel, and increase the content of other elements, such as carbon. This production phenomenon of not strictly matching the ingredients according to the model and product characteristics not only greatly reduces the quality of the product, but also affects the appearance and antioxidant properties of the product.

3. Human factors
If the user operates improperly during use and maintenance, especially in the food and chemical equipment industry, the probability of artificial oxidation of stainless steel seamless pipes is relatively high. For the artificial oxidation of steel products, one should have correct product usage knowledge and conduct regular and reasonable inspections. Effective maintenance can reduce oxidation caused by improper human operation.
