... 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...

...) tests with linear polarization resistance (LPR) method were used to get instantaneous corrosion in a simulated white liquor (WL) solution with hard particles simulating conditions for the digesters or evaporators. Repassivation behavior of alloys under flow conditions was studied by using scratch tests...

...

Corrosion products remaining on the specimen surface were examined using an optical microscope...

... INTRODUCTION ABSTRACT Duplex stainless steels (DSS) may experience environmental assisted cracking (EAC) under certain conditions in the kraft white liquor solutions used by the pulp and paper industry. Previous work showed that hydrogen absorption is possible in these solutions under...

..., accumulators, clarifiers, and white liquor storage tanks has been a major problem [2]. White liquor used in Kraft pulping process contains sodium hydroxide (NaOH) and sodium sulfide (Na 2 S) [3]. Other pulp mill liquors also contain hydroxide and sulfides but white liquor contains the highest concentrations...

... (synthetic white liquor) was evaluated. During metal fabrication processes, localized areas of DSS may be exposed to different cooling rates or aging temperatures, which may lead to a change in the microstructure or produce precipitates in these regions. This change in microstructure may in turn affect...
