WebAbstract. The corrosion of twenty-five metals and alloys by liquid and gaseous fluorine was studied. The liquid corrosion tests were performed at --320 tained F and exposure ranged from 5 hours to 3 days. Expcsures to gaseous fluorine were made at apprcximately 80, 400, 700, and 1000 tained F. Expcsure times were generally 5, 24, and 120 hours.
