A research program currently in progress at Brookhaven National Laboratory has produced quantitative data on the various factors which may influence the service life of Inconel 600 steam generator tubing. A basic model is presented to relate data produced using accelerated test methods to actual service conditions. The effects of temperature, environment, stress, strain and strain rate on a number of heats of mill annealed material and tubing with beneficial heat treatments are presented. The initiation and propagation stages of intergranular stress corrosion cracking are treated separately. Although crack initiation time is altered by different chemical environments or perhaps composition, the crack growth rates appear to be governed by a temperature dependent process.
