Passivation
In Passivation, the surface of the stainless steel is treated with an oxidizing acid, to dissolve carbon steel, sulfide inclusions and remove iron and other surface contaminants from the stainless. The acid further works to promote the formation of the chromium-rich passive film, which imparts the corrosion resistance quality
Both types of metal finishing have great advantages
• Removes impurities from metal products
• Protects the metal from penetration of pollutants causing rusting and damage
• Smoothens metal surface & reduces imperfections
• Improves metal durability
