Corrosion of Stainless Steel: Test Methods and Proper Expectations
ASTM A967 and ASTM A380 – two of the most widely recognized industry standards for passivation – list a number of methods that can be used to passivate a part; however, they do not claim to be all-encompassing. ASTM recognizes that there are many valid ways to passivate a stainless steel part.

Equivalent to QQ-P-35 spec for passivation of stainless steel? ASTM A967?
We supply formulations to many of the spring manufacturers around the world for this purpose. QQ-P-35C has been canceled in favor of ASTM A967 [affil link] for all passivation except aerospace, which should use AMS2700 [affil link]. The passivation specification for nitric in ASTM A967 [affil link] is IDENTICAL to the now defunct QQ-P spec.

According to ASTM A967, passivation is the chemical treatment of stainless steel with an oxidant agent, to remove free iron or other materials. The passivation baths commonly use citric and nitric acid as oxidizing agents. However, the latter generates toxic vapors that are harmful to health [22,23,24]. On the other hand, citric acid is ...

What is ASTM A967?
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.
Installation Guidance
In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion. At Inline design the standards we follow are ASTM A967, ASTM A380 and AMS 2700.
Passivation of Corrosion Resistant Steels
AMS 2700 has no guidelines for descaling or chemical cleaning processes detailed in ASTM A380 and ASTM A967; AMS 2700 is strictly a specification on passivation processes. ASTM A967 describes a passivation procedure must follow cleaning and / or descaling. Any contamination not removed prior to passivation reduces a part's corrosion ...
Unpacking ASTM A967
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.
