Water vapor effects on the corrosion of steel

PDF Version Also Available for Download.

Description

Critical relative humidity for AISI 1020 carbon steel is 75-85% RH at 65 C. Aggressive electrochemical corrosion occurs above 85% RH, while dry oxidation occurs below 75% RH. The reddish-brown product is probably Fe2O3 or its hydrate; the black oxide layer, Fe3O4. The face surfaces had little or no corrosion, while the mill-machined edges were corroded with nonuniform reddish-brown areas.
