Three major causes of oxidation of stainless steel

Stainless steel often occurs three reasons for oxidation phenomenon:
1, the production process: this is one of the reasons that cause the product steel products oxidation, will tell from the production process and product characteristics, the product surface forming a thin layer of oxide film is the foundation of avoid oxidizing process, and steel products is one of the main characteristics different from other steel products, but due to inadequate production technology performance due to negligence or incomplete oxidation film, discontinuity, the oxygen in air is directly with the product elements of REDOX reaction, resulting in product performance oxidation occurs.
2, the ratio of ingredients: some manufacturers to reduce production costs, thereby reducing the proportion of some important elements such as chromium, nickel content, and increase the content of other elements such as carbon, this is not in strict accordance with the product type, product characteristics for composition ratio of production phenomenon, not only to our quality of products, for example, 304 stainless steel tube chromium content of less than, not only affects the corrosion resistance and formability of the product, when it used in chemical industry, equipment, production potential of product quality and safety hidden trouble; At the same time, it also affects the appearance of the product and its antioxidant performance.

3, human factors, which is why some consumers in the use of stainless steel products * often meet product oxidation is one of the reasons, some consumers in product use improper operation and maintenance, especially some chemical equipment used for food industry of stainless steel pipe products appear the probability of human reason oxide on the high side, the artificial steel products produced by the oxidation phenomenon, to have the right product to use knowledge, and regularly carries on the reasonable and effective maintenance and maintenance, thus reducing the oxidation phenomenon caused by improper use.
