STRESS CORROSION CRACKING OF STEAM TURBINE MATERIALS

Although moderately high strength steels have, in general, performed admirably in the long time service expected of turbine components, there have been a number of instances of stress corrosion cracking in these components. This problem area is closely examined by the authors, and recent studies are reviewed. An electrochemical study of stress corrosion cracking, using constant strain rate tests under controlled electrochemical potential has led to a better understanding of the role of impurities in caustic cracking and suggests a unifying parameter for hydrogen assisted cracking in a variety of solutions.
