Corrosion morphology of 2205–2 (0.65 YS) DSS wire after 615 days of exposure (BSE-SEM images): a general overview of the corroded region, b a few deep corrosion pits that seemed to have merged beneath the surface (lacy cover), c shallow corrosion site, indicating selective corrosion (most-likely of ferrite), d SCC crack nuclei adjacent to a corroded region, e transgranular crack within a localised corrosion site, f localised corrosion with filiform type undercut corrosion morphology, g SCC adjacent to a corroded region, i several sub-micrometre sized corrosion pits at exposed grain facets
