Corrosion phenomena of alloy 625 pressure tubes were investigated in aqueous solutions containing up to 0.2 mol/kg scdfirric acid and up to 1.44 mol/kg oxygen. Applied maximum temperatures and pressures were 500 °C, and 38 MPa, respectively. Corrosion started at temperatures around 150 °C with irrtergranullar attack. Above 250 °C, the whole surface of the alloy was attacked, shallow pits and deep intergramrlar attack appeared. This behavior can be explained by transpassive dissolution of the protecting Cr(III)oxide layer and leads to severe material loss. The upper temperature limit of severe corrosion at an experimental pressure of 24 MPa was about 390 °C. As temperature was increased tiuther and the density of the solution dropped to low values, only slight corrosion was detected. Keywords: Corrosion, transpassive dissolution, intergranular attack, alloy 625, sultimic acid, oxygen, high-temperature, high-pressure, supercritical water, SCWO.
