The effect of various levels of chloride ion content in unsymmetrical dimethylhydrazine propellant on three materials was investigated. Sustained load tests were conducted at 49C 120F temperature with thin and thick gage tensile specimens with a semi-elliptical surface flaw. Alloys included aluminum, 2014T6 corrosion resistant steel type 304L and titanium, 6Al-4V. It was concluded that the chloride ion levels of the UDMH samples tested do not affect the sustained load stress corrosion crack growth properties of these alloys in the parent metal form specified for this program.
