Corrosion of alloy 625 (NiCr22Mo9Nb; 2.4856) pressure tubes was investigated in aqueous solutions of phosphoric acid (0.05 Β± 1.0 mol/kg) and oxygen (0.48 mol/kg) at temperatures up to 500 8C and pressures of 24 MPa. Reaction times were up to 185 h. At acid concentrations below 0.1 mol/kg, no corros
