Evaluation of corrosion resistance of metal alloys used as construction materials in wet limestone desulfurization of flue gas
An austenitic stainless steel and 2 Ni alloys were tested for corrosion resistance in aq. H2SO4 soln. (1 g/L) contg. NaCl (2 or 10 g/L) and NaF (0.1 to 2 g/L) by potentiodynamic polarization method. The steel was not resistant to pitting corrosion in presence of Cl- ions. The Ni alloys did not undergo corrosion even at elevated temp. (up to 80 degrees C).
