Passivation
Passivation helps extend the life and function of your components. It removes microscopic impurities from porous material, such as steel, before they become rust. Passivation also removes free iron from a part, which eliminates the number of possible corrosion points, as well as impurities and other oxides from the material's surface to help sterilize, sanitize, or clean the exposed surface. After the passivation process is complete, the material is left with a protective finish while maintaining the required tolerances.
