Passivation
Item Name Type of Process Features
Passivation Capabilities Passivation
treatments for
cleaning and
descaling
corrosion-
resistant parts,
components,
equipment and
systems.
Passivating
steel removes
all impurities
and creates a
hard non-
reactive
surface film
that inhibits
further
corrosion.
Process Approvals Material Base Materials Worked
For Passivation we adhere to:
AMS 2700: Passivation of Corrosion Resistant Steels
BAC 5625: Passivation of Corrossion
Resistant Steels (Type II)
