Abstract : The objective of this program was the assessment of storage container compatibility with N2O4, and ClF5, for periods of time up to and including 6 years of pressurized exposure. Tankage materials were aluminum alloys 2021, 2014, 2024, 2219, 6061, 7039, X7007, and 5456, as well as Arde 301 stainless steel, A-286 and Inconel 718. Two types of N2O4 were evaluated for compatibility, namely oxygenated and unoxygenated. The evaluation of the storage containers revealed that the major source of degradation was external. The primary cause of corrosion was the dilute acid, high humidity storage area environment. Internal corrosion observed in a very limited number of containers was attributable to a lack of thorough rinsing after exposure. The majority of internal surfaces showed little or no degradation from either oxidizer.
