1. The reason for the production process; this is one of the reasons that cause the oxidation of steel products.From the perspective of production technology and product characteristics, forming a thin oxide film on the surface of the product is the root process to avoid oxidation, and it is also a steel product It is different from one of the main characteristics of other steel products, but due to the lack or negligence of the production process, the oxide film is incomplete and inconsecutive. The product exhibits oxidation phenomena.

2. Reasons for product composition ratio; in order to reduce production costs, some manufacturers then reduce the share of some important elements such as chromium and nickel, while increasing the content of other elements such as carbon. This is not strictly according to product model and product characteristics The production phenomenon of ingredient ratio not only greatly reduces the quality of the product. Potential product quality and safety hazards; together, also affect the appearance and anti-oxidation performance of the product.

3. Man-made reasons; this is also one of the most common causes of product oxidation encountered by some consumers when using stainless steel products. The probability of products exhibiting artificial oxidation is high. Regarding the phenomenon of human-induced oxidation of steel products, we must have correct product use knowledge and regular protection and maintenance of it, and then reduce the oxidation caused by improper use.

Stainless steel capillary is widely used in modern times. It has the advantages of sanitation, environmental protection, economical application, simple links, etc. Although it is made of stainless steel, it will also rust under certain circumstances. The following editor summarizes for everyone:

1. There are chloride ions in the environment.

Chloride ions are widespread, such as salt, sweat, sea water, sea breeze, soil and so on. The 304 stainless steel capillary tube corrodes quickly in the environment where chloride ions exist, even more than ordinary low carbon steel. Therefore, there is a requirement for the use environment of 304 stainless steel capillaries, and it is often necessary to scrub, remove dust, and keep it clean and dry.

2. No solution treatment.

The alloy elements are not dissolved into the matrix, resulting in a low alloy content in the matrix and poor corrosion resistance.
