What is stainless steel flange chemical polishing?
The chemical polishing of stainless steel flanges is achieved by the regular dissolution of the flange surface to achieve a smooth and smooth finish.
In the chemical polishing process, the passivation oxide film and the oxide film are continuously formed on the surface of the steel stainless steel flange, and the former is stronger than the latter. Due to the microscopic inconsistency of the surface of the stainless steel flange, the microscopic convex portion of the surface is preferentially dissolved, and the dissolution rate is greater than the dissolution rate of the concave portion.
Moreover, the dissolution of the film and the formation of the film are always performed at the same time, but the rate is different, and as a result, the surface roughness of the steel stainless steel flange is leveled, thereby obtaining a smooth and bright surface. Polishing can fill surface pores, scratches and other surface defects, thereby increasing fatigue resistance and corrosion resistance.
