Description

Crevice corrosion properties of 304 Stainless Steel (304SS) and Alloy 600 in aqueous oxalic acid solution were evaluated and the results were analyzed by chemical thermodynamic calculation. The corrosion rate of 304SS in the low pH region was highly accelerated, however that of Alloy 600 was not. Crevice corrosion resistance of those alloys critically relies on the formation of protective layer (NiC2O4) which was formed on the surface of Alloy 600 only. FeC2O4 did not contribute to corrosion resistance which was formed on the surface of 304SS at the low pH region. (author)
