Stainless steel castings have the function of not rusting, and it can be seen from the production process that stainless steel castings only need to be cast with pure stainless steel liquid. After a series of processes, the castings are produced. The following describes how to ensure stainless steel castings. The mirror treatment effect.

The experimental results show that the sulfuric acid oxide film is an important factor affecting the transparency of the oxide film of stainless steel castings. Its thickness, porosity, purity, sealing quality and other factors directly affect the mirror effect of stainless steel castings. For example, the oxide film contains more impurities , The purity of stainless steel castings is low, causing the transparency of stainless steel castings to decrease.

In order to ensure the mirror treatment effect of stainless steel castings, the impurity content in the oxide film must be reduced. Therefore, the thickness, porosity, purity, and sealing quality of the film must be reasonably controlled to have a negative impact on the treatment as much as possible. However, the impurities in the oxide film mainly come from the stainless steel casting itself, and the other part comes from the oxidation tank, so the content of alloying elements in the stainless steel casting should be appropriately reduced to reduce the impurity content. Reduce the impurity ions in the bath, keep the bath fresh, and improve the purity of the oxide film.

It can be seen that it is also difficult to successfully complete the mirror surface processing technology of stainless steel castings. To achieve good results, it is necessary to eliminate various influencing factors to improve the quality of stainless steel castings.
