Stress corrosion testing of high strength steels and alloys missile case materials was continued. The samples tested were D6Ac, 300M, Vascojet 1000, AM 355, PH 15-7 Mo, B120VCA, 4137 Co, Rocoloy 270, and Ardeform 301. The results of treating PH 15-7 Mo, Vascojet 1000, and D6Ac are presented. No corrosion failures of these samples were recorded. Data on the exposure of specimens to marine, semi-industrial, and industrial environments are reported. For 4137 Co tempered at 75 maximum yield strength provided immunity from stress corrosion up to the yield point. The cumulative results for AM 355, PH 15-7Mo, B120VCA, 4137 Co, and Ardeform 301 are included.
