The effect of stress intensity, yield strength and temperature on the growth rates of stress corrosion cracks in 3.5NiCrMoV and other steam turbine rotor steels has been reassessed. It is shown that from 60 C to 170 C the upper limit of laboratory test results in deaerated water coincides with the upper limit of stress corrosion service experience with steam turbine rotors in the field. This permits a conservative estimate of the residual lifetime of cracked components on the basis of laboratory test results.
