Static and Dynamic Tests Effect of Nitrogen Tetroxide On Metals and Plastics^★ Available to Purchase

The corrosion rates of carbon steel, stainless steel (304-L and PH 15-7 Mo), aluminum (5086), and titanium (75A and 6A1-4V) in dry and wet nitrogen tetroxide were determined under static conditions of exposure at —9 C to 74 C. Carbon steel and aluminum were attacked in proportion to water concentration and temperature. Stainless steel 304-L and titanium were unattacked, and PH 15-7 Mo only slightly attacked. Significant corrosion of stainless steel (304-L) occurred in the presence of Teflon. Corrosion by dry nitrogen tetroxide under flow conditions was negligible. Teflon was the most resistant of the plastics exposed to nitrogen tetroxide. 4.3.3
