Abstract:

Cumulative stress corrosion test data for the various bent beam and U-bend tests on high strength missile alloys are given. Included are bent beam data for D6Ac, Vascojet 1000, AM355, PH15-7 Mo, B120VCA, and 4137 Co and U-bend data for 300M, AM355, PH15-7 Mo, B120VCA, 4137 Co, Ardeform 301, and U-modified 4137 Co. While testing is not complete and has not progressed to a sufficient degree in all cases for adequate summation, the low alloy steels 4137 Co, 300M, and Vascojet 1000 are definitely susceptible to stress corro ion in varying degree. The M355, PH15-7 Mo, B120VCA, and Ardeform 301 alloys are not susceptible, regardless of strength level of exposure. Alloy odificatio of the 4137 Co wi h U m rk dly ecreased the stress corrosion susceptibility of this alloy.
