Cleaning removes oils, dirt, welding residue, and other surface contaminants to ensure the passivation process works effectively and provides consistent results.
We primarily provide cleaning and passivation for:
Stainless steel components
Fabricated stainless assemblies
Welded parts and surfaces
Passivation helps prevent rust, corrosion, and surface discoloration by restoring the natural protective layer on stainless steel after machining, grinding, or welding.
Passivation is a chemical treatment process used to improve the corrosion resistance of stainless steel by removing surface contaminants and enhancing the protective oxide layer.
Our cleaning and passivation services support a wide range of American manufacturing industries, including:
Each industry relies on clean, corrosion-resistant components to maintain safety, performance, and reliability.
Cleaning and passivation are critical steps in delivering precision machined parts that perform as intended over their full service life. At Caldwell Manufacturing, these processes are handled with the same attention to detail as machining itself.
If your components require controlled cleanliness and corrosion protection you can rely on, we are ready to help. Send us your drawing, request a quote, and let us deliver parts that meet specification from surface to core.
