The crack growth rates (CGRs) of a forged nuclear grade 316L SS piping material l were measured at various temperatures and loading modes in oxygenated high-temperature water. A direct current potential drop technique was used to monitor the CGRs throughout the tests. The fracture surface of crack advance under stress corrosion conditions exhibited typical intergranular stress corrosion cracking characteristics. CGRs increased monotonically with increasing temperature. CGRs under trapezoidal waveform loading were moderately higher than those under constant K loading. (C) 2014 Elsevier Ltd.
