Corrosive bleaching processes require strong, chloride resistant fasteners
The pulp and paper industry uses thousands of gallons of bleach a day to produce the vivid white paper that offices and schools depend on. Chlorine, chlorine oxide or chlor alkali; no matter its form, bleach and the various forms of chlorinated compounds are corrosive.
Corrosion Focus
From digesters and evaporators, to boilers and storage takes, components in the pulp & paper industry are exposed to chloride corrosion. To combat corrosion from bleach, similar materials are used compared with salt water and marine corrosion.
AL6XN bolts were developed for marine use, but perform well in pulp & paper for their chloride resistance
Titanium Grade 2 fasteners are highly effective in this environment for their resistance to chlorides, chlorines, and chlorine chemicals.
Duplex 2507 offers high resistance to pitting, erosion and crevice corrosion, as well as stress corrosion cracking in chlorides
