Passivation is a crucial step in boosting corrosion resistance of stainless steel parts and components. Passivation returns the substrate back to its original specifications through cleaning the substrate of oils and removing iron particles from the surface. TPI has a climate-controlled clean room for the passivation of sensitive medical and electronic industry parts.
