Abstract

Austenitic stainless steels necessary for resistance to sulfur and organic acids have failed by stress corrosion cracking and by general and localized surface attack. These failures are attributed to polythionic acids and chlorides occurring in or adjacent to weldments. Other types of failures relating to weldments and weld overlays are also described. The differences and similarities between the petroleum refinery and coal liquefaction technologies are addressed as they relate to welding. Current research projects aimed at improving weldability are also discussed.
