Passivation & Chromating Services
MIP, Inc. delivers high-quality passivating and chromating services to a wide range of industries.
Passivation of stainless steel is a process performed to make a surface passive. This is done by removing exogenous iron or iron compounds from the surface of stainless steel using nitric chemical dissolution. Passivation has the capability to increase the corrosion resistance of stainless surfaces.
The passivation of stainless steel is performed when free iron, rust, iron particles, metal chips or other nonvolatile deposits might adversely affect the metallurgical or sanitary condition or stability of the stainless surface or the mechanical operation of a part, component, or system.
The process is performed by initially cleaning the surface with solvents or an alkaline solution to remove organic and other metallic residues. Subsequently, the parts are dipped into passivation solutions which are typically nitric acid based. The process is controlled by time, temperature, and concentration.
