ResultPassivation of Stainless Steel to ASTM A967. Five nitric and citric methods are listed as follows: Nitric 1: 20-25 v% Nitric Acid, 2.5 w% Sodium Dichromate, 120-130F, 20 Mins minimum. Nitric 2: 20-45 v% Nitric Acid, 70-90F, 30 Mins minimum. Nitric 3: 20-25 v% Nitric Acid, 120-140F, 20 Mins minimum.
ResultASTM 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 …
