The difference in stress corrosion cracking (SCC) susceptibility between high and low interstitial ferritic stainless steels (SS) (26Cr-1Mo) in chloride solutions is the result of the relation between their corrosion and cracking potentials. Changes in the initial state of a normally immune low interstitial steel (E-Brite)(R) either by heat treatment or prior deformation will induce susceptibility to SCC. On loading, transient creep produced breaks in the protective film in the ...
