Chloride Stress Corrosion Cracking

Abstract A case history is given of failures of stainless steel deaerator trays used in a deaerating feed water heater. Trays fabricated from Type 201 and Type 329 stainless steels were reported to have failed by chloride stress corrosion cracking after several months' service. The cracking of the Type 201 was very severe. It is shown that conditions in parts of the deaerating heater promote failure by chloride stress corrosion cracking and the service life of austenitic stainless steels is very short. Annealing after welding of the Type 329 trays would improve resistance to cracking. It is also suggested that Type 430 stainless steel be considered since it is not susceptible to chloride stress corrosion cracking. 6.2.5, 3.5.8, 7.6.8
