Influence of oxide films on primary water stress corrosion cracking initiation of alloy 600 [PDF]

, 2006
In the present study alloy 600 was tested in simulated pressurised water reactor (PWR) primary water, at 360 °C, under an hydrogen partial pressure of 30 kPa. These testing conditions correspond to the maximum sensitivity of alloy 600 to crack initiation.
