The "stainless steel passivation treatment" is a surface treatment that makes stainless steel more resistant to rust. This technology forms a strong and stable passive film on the surface by immersing the product in a solution with strong oxidizing power under specific conditions. It strengthens the passivation film on the stainless steel surface and improves corrosion resistance. 【Features】 ■ It is possible to further enhance the corrosion resistance of stainless steel. ■ There is almost no change in product appearance or dimensions. ■ Excellent cleaning effect allows for the removal of contaminants, such as dissimilar metals, which can be the starting point for corrosion on the surface of parts. ■ Further improvement in corrosion resistance can be achieved when used in conjunction with electropolishing. ■ Effective for most types of stainless steel. *Some types of stainless steel may not be suitable for treatment, or it is recommended to use it in conjunction with electropolishing. *For more details, please refer to the PDF document or feel free to contact us.
