Product Sheet: Passivation Services

Allegheny Surface Technology offers citric and nitric passivation. They can handle almost any size and shape. If you can't send it to them, Allegheny Surface Technology can go on-site. They passivate vessels, pipes, tubing, manifolds, frames and architectural components, and enclosures, just to name a few.

Passivation is the chemical process that removes free irons from the surface of your stainless steel. This creates a chromium rich surface which can form an invisible inert (passive) oxide fill as soon as it is exposed to an oxygen-containing environment (air). Allegheny Surface uses citric and nitric passivation solutions.
