Nitric vs. Citric Acid Passivation for Stainless Steel (SS) & Ti

Since both of the most-used standards derived from the QQ-P-35 military standard of the 1960s, questions often arise about the differences between ASTM A967 vs. AMS 2700. These standards are essentially equivalent, and differ by who uses them. The aerospace industry tends to use AMS 2700, while other industries use ASTM A967.
