Six alloys are being evaluated in 11 different environments. Specimens of Ladish D6AC, Type 300M, and Vascojet 1000 alloy steels, AM355 and PH 15-7 Mo stainless steels, and B120VCA Ti alloy are being tested in air, distilled water, tap water, 0.25 sodium dichromate solution, 1 marquench salt solution, 3 sodium chloride solution, trichloroethylene, cosmoline, 4 soluble oil solution, high humidity atmosphere, and solid propellant. No failures were observed with any of the specimens exposed to laboratory air, the sodium dichromate solution, the marquench salt solution, the solution of Chevrons soluble oil, or the high humidity. An environment of distilled water was the most conducive to stresscorrosion cracking. Some failures were observed in all the other environments.
