PASSIVATION OF STAINLESS STEEL

Passivation is the removal of exogenous iron or iron compounds from a stainless steel surface by means of a chemical dissolution. Passivation is accomplished by removing surface contaminates in a chemical bath without significantly affecting the stainless steel. After the parts have been run through the passivation bath, a passive film is spontaneously formed. This passive film improves the corrosion resistance of the stainless steel.

The chemical baths utilized at Arrow Cryogenics allow us to certify to many different passivation specifications.
