For example, ASTM A967 contains more options for passivation verification tests while AMS2700 provides more guidance on sampling large batches of components for testing and inspection after passivation. As the most direct linear descendant of QQ-P-35, AMS 2700 naturally shows its "heritage". QQ-P-35 types II, VI, VII and VIII are equivalent ...
1. Passivation Process: ASTM A967 defines the passivation process as the removal of free iron or other foreign matter from the surface of stainless steel by means of a chemical treatment. This treatment encourages the formation of a passive oxide layer, strengthening the steel's resistance to corrosion. 2.

Passivation is the process of creating a corrosion-resistant layer on metal surfaces by treating them with an acid bath. American Bright Works offers passivation services which include citric and nitric acid passivation tanks and post passivation testing in accordance with ASTM A967-17.
35A, AMS 2700C, ASTM A 967-05 and ASTM A 380-06 standards. 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.
