Stress corrosion testing methods

A critical review of stress corrosion testing is proposed. It would appear desirable for stress corrosion tests to use solutions where initial passivation conditions are close to those met with in practice. This is particularly important if the tests aim at classifying different grades of steel with regard to their stress corrosion cracking susceptibility.
The slow strain rate tests are severe type of tests which must be better exploited. Progress is to be made in the characterization of the SCC behaviour by the knowledge of the dynamic behaviour of the passive layer.
Finally the distinction between stress corrosion testing and corrosion fatigue testing is discussed.
