AMS 2700 does not allow for a user-defined set of passivation parameters (A967 Nitric Methods 4 & 5, Citric Methods 4 & 5) even if they are proven to pass a verification test. This is AMS 2700's greatest procedural difference from ASTM A967. With AMS 2700's larger variety of qualified parameters, one of the sets must be followed.

Type 304L Stainless Steel. Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for …

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.
