Abstract
Specimens of duplex stainless steel (DSS) were exposed at temperature of 200°C in industrial white liquor from a Brazilian kraft mill using an autoclave to simulate the same conditions of a digester processing. Tafel extrapolation method and weight loss were used to evaluate corrosion behavior of duplex steel in white liquor. The corrosion rates of DSSs increase as the temperature increases. Moreover, selective dissolution of the ferrite phase occurred.
