ASTM A967. General industries use this standard to describe and control the passivation of stainless steel. Passivation is a process of making stainless steel more stainless than it would be if left alone. It is based on using an acid (nitric or citric) under highly controlled conditions to remove free iron particles from the surface and to help form a metal oxide …

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.

Passivation 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.
