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.

One is a commercially available citric acid passivation solution that contains citric acid and cleaning compounds and meets ASTM A 967 (Citric 4), and the other two passivation solutions are Type II and Type VII from AMS-QQ-P-35. These AMS-QQ-P-35 solutions are used by the aerospace industry to passivate stainless steel parts.

La norme ASTM A967 propose des tests comportant des critères de validation démontrant que les procédures de passivation ont été couronnées de succès. Selon les normes internationales ASTM, « les tests de passivation représentent le processus par lequel l'acier inoxydable forme
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.
