There are usually three reasons for stainless steel oxidation:

1. Reasons for consumption process: This is one of the reasons for the oxidation of by-product steel. The process and product characteristics come from consumption. The formation of a thin oxide film on the product appearance is a warp and weft process to prevent oxidation wrinkling. One of the main characteristics of steel products is that they are different from other steel products, but lack or neglect in the consumption process, resulting in incomplete and discontinuous oxide film, Oxygen in the air directly combines with some elements in the product, resulting in oxidation of the product.

2. Reasons for product composition ratio: in order to reduce consumption funds, reduce the proportion and content of some important elements such as chromium and nickel, and increase the content of other elements such as carbon, some manufacturers strictly follow the product model and product characteristics to prevent the consumption of ingredients ratio, which not only leads to quality discount, such as the lack of chromium content in 304 stainless steel pipe, It not only affects the corrosion resistance and formability of products, but also has hidden dangers in production quality and safety in chemical, equipment and consumer industries; At the same time, it also affects the appearance and oxidation resistance of products.

The improper use of stainless steel tubes is one of the reasons that people often encounter in the production and maintenance of some stainless steel products, especially in the chemical industry, Have correct product use knowledge and stop reasonable and effective maintenance regularly, so as to reduce the oxidation phenomenon of improper manual use.
