Abstract
Stress corrosion cracking (SCC) susceptibility of various solution annealed, non-sensitized, austenitic stainless steels was examined in high temperature water using creviced bent beam (CBB) and creviced uniaxial constant load (UCL) tests. The following results were obtained in this study.
(1) 304, 304L, 316L, 316NG and 347NG were susceptible to SCC under the crevice and high applied stress conditions.
(2) Deformation induced martensite is not necessary but accelerating factor for SCC in various solution annealed austenitic stainless steels.
(3) CBB test and creviced UCL test give different results on the effect of cold work on the SCC susceptibility in various solution annealed austenitic stainless steels because of the difference in strain under their test conditions.
