The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Per passivation standard, ASTM A967 requires the parts to be immediately neutralized post immersion followed by a chemical treatment to treat the surface of the part. ASTM approved tests may include:
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 …

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.

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 ...
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.
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.
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 …
