Abstract
The monitoring of localized corrosion of stainless steels in chemical plants by measuring the spontaneous corrosion potential of the equipment itself is discussed concerning the monitoring principle and points to be remarked in the measruements. Variations in corrosion potential with time measured for fermentors and evaporators under the operating conditions are shown to monitor the possibility of occurrence of localized corrosion such as pitting and crevice corrosion.
