Popis:	1. Failure of heat exchangers made of steels Kh23N18 and Kh24N12SL results from carburizing and sulfur-alkali corrosion in the presence of compounds of vanadium forming a low-melting eutectic preferentially in austenite grain boundaries. 2. The corrosion rate of heat exchangers in mazout furnaces is three times the corrosion rate of heat exchangers in gas furnaces. 3. In heat exchangers that increase the gas flow rate the surface is attacked due to erosion-abrasion of the protective oxide film. Free oxidation and carburizing of the steel occur in this case.
