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.

Both AMS 2700 and ASTM A967 base their nitric acid passivation methods on using 42° Baume nitric acid. The Baume scale is a measurement of specific gravity. Positive degrees of Baume indicate chemicals or solutions denser than water. 42° Baume nitric acid corresponds to a 1.4 specific gravity solution of nitric acid that is roughly 67% …

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.

35A, AMS 2700C, ASTM A 967-05 and ASTM A 380-06 standards. Passivation alone will not remove heavy adherent oxide films created from heat treatment, welding, hot-forming and other high-temperature operations. Therefore AST uses different types of pickling acids designed to remove these films prior to the Passivation of the parts.

1. Passivation Process: ASTM A967 defines the passivation process as the removal of free iron or other foreign matter from the surface of stainless steel by means of a chemical treatment. This treatment encourages the formation of a passive oxide layer, strengthening the steel's resistance to corrosion. 2.
