Three major reasons for oxidation of stainless steel

- Jul 17, 2019-

1. Production process reasons: This is one of the causes of oxidation of steel products. From the perspective of production process and product characteristics, forming a thin oxide film on the surface of the product is the basic process to avoid oxidation and steel products. Different from one of the main features of other steel products, but when the production process is insufficient or inadvertent, the oxygen film in the air directly undergoes redox reaction with some elements in the product, resulting in incomplete or discontinuous oxide film. The product exhibits oxidation.


2, the proportion of product ingredients: some manufacturers in order to reduce production costs, 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 In order to produce the proportion of products, the quality of the products is greatly reduced. For example, when the content of chromium in the 304 stainless steel tube is insufficient, it not only affects the corrosion resistance and formability of the product, but also exists in the chemical, equipment, and production industries. Potential product quality and safety hazards; at the same time, it also affects the appearance and oxidation resistance of the product.


3, human reasons: This is one of the reasons why some consumers often encounter the oxidation of products when using stainless steel products, some consumers are improperly used in product use and maintenance, especially some stainless steel pipe products used in food chemical equipment industry The probability of occurrence of artificial oxidation is high. For the artificial oxidation of steel products, it is necessary to have the correct knowledge of product use and regular and effective maintenance and maintenance, so as to reduce the oxidation caused by improper use of humans.
