Abstract

Some electrochemical aspects of the stress corrosion cracking (SCC) behavior of ASTM A517 Grade F steel in liquid ammonia environments at 25 C have been studied. Electrode potentials were measured during SCC tests by means of thallium/saturated thallous chloride/ammonia reference half cell. The effects of controlled additions of oxygen and nitrogen (species in combination known to cause SCC), as well as the inhibitive properties of water, were investigated. The role of water as an inhibitor is to assist in the repassivation of the surface films, as indicated by the fact that water additions promote more noble potentials ( plus 500 mV).
