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.

Introduction to ASTM A967. All types of stainless steel components are intended to have their corrosion resistance improved by ASTM A967 for chemical passivation treatments. ASTM A967 deals with the problem of iron or foreign particles that may stick/embed in the surface during processing and, if not removed, may result in the development of rust or …

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.

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.

ASTM A967 and ASTM A380 have similar mechanical properties. Both materials have a yield strength of 205 MPa and a tensile strength of 520 MPa. The main difference is that ASTM A967 has a higher elongation at break (10%) than ASTM A380 (8%). This means that ASTM A967 is more ductile than ASTM A380 and is better suited …
