    Abstract

    The environment causing stress-corrosion cracking (SCC) at the top of a distillation tower in a crude oil refinery was reproduced in the laboratory. It was an acidified hydrogen sulfide solution with a pH value up to 3.5 at 80°C. In the solution, austenitic stainless steels such as AISI Type 304 or 316 failed because of SCC; however, modified ferritic stainless steels showed good corrosion resistance.
