Potentiostatic anodic polarization curves were used to study the pitting resistance of American Iron and Steel Institute (AISI) Type 420 (Unified Numbering System [UNS] S42000) stainless steel in solutions containing bicarbonate, sodium chloride, hydrogen sulfide, and carbon dioxide. The effect of applied potential on the sulfide stress cracking (SSC) of this material was also investigated. The appropriateness of the test solution, described in the National Association of Corrosion Engineers (NACE) (TM-01-77), for determining the SSC of Type 420 stainless steel is then evaluated in light of the results of this investigation.
