With our advanced techniques and state-of-the-art facilities, we deliver superior quality, precision, and durability in every passivation and electropolishing application.

What is Stainless Steel Passivation?

Stainless steel passivation is a chemical process that removes free iron and contaminants from the surface of stainless steel, enhancing its corrosion resistance and extending its lifespan. Passivation forms a protective oxide layer on the surface of the stainless steel, preventing rust, staining, and corrosion in harsh environments.

The Passivation Process

CleaningBefore passivation, thorough cleaning of the stainless steel surface is essential to remove any dirt, grease, or debris that could interfere with the passivation process.

Acid TreatmentThe stainless steel components are immersed in a passivating solution, typically an acidic mixture containing nitric acid or citric acid. This solution removes free iron and other surface contaminants, promoting the formation of a passive oxide layer.

Rinsing and DryingAfter passivation, the components are rinsed thoroughly to remove any residual passivating solution and then dried to prevent water spots or contamination.

Benefits of Stainless Steel Passivation

Enhanced Corrosion ResistancePassivation improves the corrosion resistance of stainless steel by removing surface contaminants and promoting the formation of a protective oxide layer.

Extended LifespanPassivated stainless steel components are less susceptible to rust, staining, and corrosion, resulting in a longer lifespan and reduced maintenance requirements.

Improved Aesthetic AppearancePassivation leaves the surface of stainless steel clean, smooth, and free of discoloration, enhancing its aesthetic appeal and maintaining its appearance over time.

What is Electropolishing?

Electropolishing is an electrochemical process that removes a thin layer of surface material from stainless steel through controlled anodic dissolution. This process produces a smooth, bright, and highly reflective surface finish, improving corrosion resistance, cleanliness, and aesthetics.

The Electropolishing Process

PreparationSimilar to passivation, thorough cleaning of the stainless steel surface is crucial before electropolishing to remove any contaminants and ensure optimal results.

ElectropolishingThe stainless steel components are immersed in an electrolyte solution and subjected to an electric current. This causes material to be removed from the surface of the stainless steel, resulting in a smooth, bright finish.

Rinsing and DryingAfter electropolishing, the components are rinsed thoroughly to remove any residual electrolyte solution and then dried to prevent water spots or contamination.

Benefits of Electropolishing

Improved Surface FinishElectropolishing produces a smooth, bright, and highly reflective surface finish, enhancing the aesthetic appearance of stainless steel components.

Increased Corrosion Resistance: The removal of surface material during electropolishing improves the passivity of stainless steel, enhancing its corrosion resistance and durability.

Cleanliness and HygieneElectropolished surfaces are easier to clean and maintain, making them ideal for applications requiring high levels of cleanliness and hygiene.
