Results from an ongoing FGD scrubber exposure program to assess the performance of titanium, stainless, and nickel-base alloys are presented and discussed. Spool rack exposures in corrosive inlet quench and outlet duct areas of several power plant FGD scrubbers allowed comparison of the corrosion resistance of the alloys. In general, Titanium Grades 2 and 12 equaled and often exceeded the corrosion resistance of the stainless and nickel-base alloys. Titanium Grade 7 exhibited the best performance in the wet/dry zone of the inlet quench of a closed-loop scrubber. The stainless steels exhibited generally poor resistance to localized attack, while the performance of the nickel-base alloys was varied.
