Abstract
The occurrence of atmospheric chloride-induced stress corrosion cracking (AISCC) in types 304L and 316L austenitic stainless steels has been investigated under controlled conditions of tensile stress, chloride-salt deposition density (μg cm -2 of MgCl 2), temperature and relative humidity. Tensile specimens fashioned from 304L exhibited severe attack with several sensitized specimens undergoing complete failure in a matter of days. However, similar specimens of 316L showed no evidence of AISCC or, for that matter, any trace of localized corrosion throughout the test period of 600 hours; although a U-bend specimen of this latter material did undergo cracking. Cracks in all cases were predominantly trans-granular in nature, appeared to be associated with sites of localized corrosion and to propagate in the direction of the crystallographic planes.
