Corrosion studies were conducted on stainless steel types 347 and Carpenter-20, Monel, titanium 55A, and tsntalum in decontamination solutions. These solutions are: 10% nitric acid, 10% citric acid, 10% sodium hydroxide--2.5% tartaric acid, 10% oxalic acid, 0.003M periodic acid in 0.05M nitric acid, 3% sodium fluoride --20% nitric acid, Turco 4501 and Turco 4502, and 0.25M phosphoric acid. Boron stainless steel type 304L was studied in 10% sodium hydroxide--2.5% tartaric acid, 10 and 60% nitric acids, Turco 4501 and Turco 4502. The two austenitic stainless steels were found to be acceptable construction materials for handling each of the decontamination solutions except 3% sodium fluoride--20% nitric acid. Special limitations are defined for Monel, titanium 55A, and tantalum when exposed to decontamination reagents. (auth
