We
offer three types of stainless steel passivating depending
on your requirements:
- nitric acid
passivation
- nitric acid
with sodium dichromate passivation
- citric acid
passivation
Overview: The
stainless steel passivation process removes all surface impurities
and stimulates the development of an oxide film which protects
the component from rust and corrosion. In general all tanks
are made up specifically for the job at hand which means you
can always be assured of a fresh solution.
Tanks: We
offer tank sizes up to 6' x 5' x 3'.
Pretreatment: All
components are pretreated with a degreaser to remove grease,
oils, coolants, machining chips and other microscopic contaminants.
Nitric
Acid Passivation: Suited to Chromium-Nickel Grades
(300 Series) and Grades with 17% Chromium or more (except 440
Series).
Nitric
Acid with Sodium Dichromate Passivation: Suited
to straight
Chromium Grades (12-14% Chromium), High Carbon-High Chromium
Grades (440 Series) and Precipitation Hardening Stainless.
Citric
Acid Passivation: Suited to free-machining stainless
steels.
