AMS 2700 has no guidelines for descaling or chemical cleaning processes detailed in ASTM A380 and ASTM A967; AMS 2700 is strictly a specification on passivation processes. ASTM A967 describes a passivation procedure must follow cleaning and / or descaling. Any contamination not removed prior to passivation reduces a part's corrosion ...

The chromium combines with oxygen to form chromium oxide (Cr2O3 - two atoms of chromium and three of oxygen, though there is another form of chromium oxide with one atom of chromium and one of oxygen). Although a passive layer forms naturally in alloys with a chromium content of between 10.5% and 12%, stainless steel equipment …

The following spec refers to ASTM A380 for passivation of stainless steel and thus allows the use of ASTM A967: MIL-DTL-14072D/E/F (Table IV. Finish E300) The spec MIL-T-704K in section 3.2.6 directly describes a passivation process analogous to QQ-P-35's type II followed by a chromate post-treatment. However, QQ-P-35 assigns this process as ...

The passivation process was carried out under the specification ASTM A967-17 . Gaydos et al. reported that extended passivation treatments give a better protection against corrosion for a series of stainless steels. In the present work, two passivation baths (a) nitric acid (20%v) and (b) citric acid (15%v) solutions were used.
