ASTM A967 vs. AMS 2700? Which is the right passivation spec?

A. As Ken says, ASTM A380 [affil link] should not be used as a passivation specification, and QQ-P-35 has been canceled. The 3 consensus specifications used at this time, and that should be used for all specifications of passivation are: ASTM F86 [affil link] for Orthopedic implants, AMS2700 [affil link] for Aerospace, ASTM A967 [affil link ...

Passivation of Corrosion Resistant Steels

Both AMS 2700 and ASTM A967 base their nitric acid passivation methods on using 42° Baume nitric acid. The Baume scale is a measurement of specific gravity. Positive degrees of Baume indicate chemicals or solutions denser than water. 42° Baume nitric acid corresponds to a 1.4 specific gravity solution of nitric acid that is roughly 67% …

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.

Corrosion of Stainless Steel: Test Methods and Proper Expectations

Per ASTM A967 and A380, stainless parts are shown to be properly passivated if they resist corrosion in salt spray for just 2 hours. Stainless steel performs relatively poorly in salt spray because the constant exposure to a harsh environment rapidly erodes the passivation layer and prevents it from reforming.

ASTM A967 vs ASTM A380

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 …

Polishing & Passivation of Titanium -- ASTM A967

A. ASTM A967 [affil link] is often specified for passivation of titanium, although it is a misnomer for sure.
