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.
