    Description / Table of Contents: Lochfraß an einem austenitischen Stahl. Wärmetauscher in einer Schwefelsäurefabrik waren mit Rohren aus Nicrofer 3620 bestückt. Als Kühlmedium diente Meerwasser. Innerhalb 5 Wochen nach Inbetriebnahme fielen mehrere Rohre durch Lochfraß aus. Dies bestätigt erneut, daß rostbeständige Stähle ohne Molybdän für derartige Einsatzfälle nicht geeignet sind.
    Notes: 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.
    Additional Material: 9 Ill.
