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.
The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. Stainless steel passivation performed to the ASTM A967 standards meets these standards by passing …

For example, ASTM A967 contains more options for passivation verification tests while AMS2700 provides more guidance on sampling large batches of components for testing and inspection after passivation. As the most direct linear descendant of QQ-P-35, AMS 2700 naturally shows its "heritage". QQ-P-35 types II, VI, VII and VIII are equivalent ...
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 ...

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.
