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 …
The standards of ASTM A967 provide specific details of the acceptable methods required for passivating stainless steel. The passivation standards listed in the ASTM document …
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.
