Abstract

Stress corrosion cracking growth rate of uni-directionally cold-rolled 316L stainless steel was monitored in simulated PWR primary water with different dissolved hydrogen (DH) concentrations at 320°C. Crack growth rate at a DH of 0.16cm3 (STP) H2/kg H2O is close to that at 5cm3 (STP) H2/kg H2O. Crack growth rate at 30cm3 (STP) H2/kg H2O is about one fourth of that at 5cm3 (STP) H2/kg H2O or two times of that at 50cm3 (STP) H2/kg H2O. Electron back scattering diffraction results show typical intergranular SCC along high angle boundaries with high levels of deformation.
