An important element that affects the purity and transparency of the oxide film on stainless steel precision castings. Its thickness, porosity, purity, and sealing quality can directly interfere with the mirror effect of the casting. For example, when there are many impurities in the oxide film, its purity will decrease and the transparency of the cylinder will decrease.
To ensure the mirror treatment effect of stainless steel precision casting parts, it is necessary to reduce the impurity content in the oxide film. Therefore, it is necessary to reasonably control the thickness, porosity, purity, and sealing quality of the film, and try not to affect the processing as much as possible. The impurities in the oxide film of stainless steel precision casting mainly come from the stainless steel precision casting itself, and some come from the oxidation bath. Therefore, appropriately reducing the content of alloying elements in castings can minimize the impurity content as much as possible. Stainless steel precision casting is a casting process with little or no cutting, which is an excellent process technology in the casting industry. Its application is very extensive, not only suitable for casting various types and alloys.
The mirror treatment process of stainless steel precision castings is also difficult to complete smoothly. To achieve good results, it is necessary to remove various influencing factors and enable the process to play a good role, so that the quality of the entire stainless steel precision casting will also be correspondingly improved.
