Book excerpt: The susceptibility of six stainless steels to stress corrosion has been determined by exposing self-stressed specimens indoors and outdoors at ambient temperatures and also at 550 F (56l K). The salt-coated stainless steels were resistant to stress corrosion cracking at 550 F (56l K) for exposures from 4000 to 10,000 hours. Specimens of AM-350 DA and AM-367 stainless steel were found to be very susceptible to stress-corrosion cracking with exposures less than 5000 hours in both the indoor (with a salt coating) and outdoor (with and without a salt coating) environments, while the AM-350 CRT, AISI 501, PH l5-7 Mo, and PH 14-8 Mo displayed excellent resistance. In general, the stainless steels with higher austenite contents appeared to have better resistance to the corrosive effects of salt, both at rooni temperature and at 550 F (56l K).
