ResultHere, we explore the passivation techniques specified by ASTM A967, AMS 2700, and QQ-P-35. ASTM A967: Five nitric acid methods are outlined: 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;
What is ASTM A967?
Result1. 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.
Unpacking ASTM A967
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 …
