Stainless Steel Passivation

Stainless steel passivation is a metal treatment technology that protects the substrate from oxidative corrosion by forming a stable passivated film on the surface of the stainless steel.

This technique significantly reduces the rate of corrosion by allowing the stainless steel surface to react with the passivator to form a dense oxide film. Stainless steel passivator is a kind of chemical substance to prevent the surface oxidation of stainless steel parts, can achieve the anti-corrosion effect, widely used in various fields of stainless steel material workpiece treatment.

The specific methods of stainless steel passivation treatment include pickling passivation and passivation solution treatment. Pickling passivation is a chemical process to remove oxides from the surface layer of stainless steel, applicable to 200 series, 300 series and 400 series stainless steel. Pickling passivation paste and pickling passivation solution are commonly used for immersion operations on small workpieces.

Stainless steel passivation has a wide range of applications in industry, which can significantly improve the corrosion resistance of stainless steel and extend its service life. In addition, the surface of stainless steel becomes smoother after passivation treatment, which helps to improve its appearance quality.
