Passivation of Corrosion Resistant Steels
AMS 2700 has no guidelines for descaling or chemical cleaning processes detailed in ASTM A380 and ASTM A967; AMS 2700 is strictly a specification on passivation processes. ASTM A967 describes a passivation procedure must follow cleaning and / or descaling. Any contamination not removed prior to passivation reduces a part's corrosion ...

Unpacking ASTM A967
ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.

Installation Guidance
In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion. At Inline design the standards we follow are ASTM A967, ASTM A380 and AMS 2700.
