A sulfuric acid plant was equipped with heat exchangers with Nicrofer 3620 tubing. The cooling medium was sea water. Within 5 weeks after start‐up some of the tubes failed by pitting, showing that it is impossible to use stainless steel as a heat transfer material in sea water unless the molybdenum content is very high.
