STRESS CORROSION OF HIGH STRENGTH STEELS AND ALLOYS; ARTIFICIAL ENVIRONMENT.

Abstract

A study of the susceptibility of various high strength missile materials to stress corrosion cracking in a number of synthetic environments was performed. In general, all low alloy martensitic steels showed a susceptibility to stress corrosion failure in varying degree, D6Ac being the least susceptible and Vascojet 1000 being the most susceptible. Of the higher alloy samples, AM355 and Ardeform 301 showed a possible susceptibility in the synthetic chloride environment. The PH15-7Mo and B120VCA were not prone to stress corrosion failure. A decarburized surface decreased failure rate in U-bends by several orders of magnitude and alloying with uranium effected a U-bend failure rate decrease of well over one order of magnitude. In general, organic coatings were not too effective in inhibiting stress corrosion failure, one or two coatings being somewhat superior to the others. The more promising combinations of coating variables are indicated. (Author)
