Abstract
Although INCONEL* nickel-chromium-molybdenum alloy 625 has good resistance to sensitization caused by carbide precipitation, some sampies of the material have been found to have less resistance than others. Laboratory studies of the precipitation reactions in the alloy give no indication that any particular phase is responsible for the increased corrosion rate. The studies do show, however, that the degree of sensitization is related to the total chromium content of the precipitates, and that control of processing, particularly annealing procedures, can produce material having maximum resistance to sensitization.
