Abstract The effects of various material and environmental factors on the intergranular stress corrosion cracking(IGSCC) susceptibility of sensitixed type 304 stainless steel in NaCl solutions were studied.The repassivation potential for SCC(ER.scc) strongly depends upon the degree of sensitization of the material,NaCl concentration,testing temperature and applied stress level for the sensitized specimens.ER.scc is more negative than repassivation potential for crevice corrosion ER.CREV The range of potential leading to cracking always stud from the level equal to ER.scc and errands to higher potential levels. But no cracking occurs at potenttials below ER.scc'The applicability of the ER.scc to evaluating the susceptibilityto SCC for the sensitized 304 stainless steel has been confirmed in this study.
