Corrosion fatigue crack growth (FCG) behavior of 316LN stainless steel was investigated in hightemperaturepressurized water at different temperatures, load ratios (R ¼ Kmax/Kmin) and rise times(tR). The environmental assisted effect on FCG rate was observed when both the R and tR exceeded theircritical values. The FCG rate showed a linear relation with stress intensity factor range (DK) in doublelogarithmic coordinate. The environmental assisted effect on FCG rate depended on the DK and quantitativerelations were proposed. Possible mechanisms of environmental assisted FCG rate underdifferent testing conditions are also discussed
