A Lake Charles, Louisiana chlorine production facility selected Titanium-0.1 Ruthenium (ASTM Grade 26) to combat crevice corrosion in the acidic chloride environment in components of a chlorine gas separation box used in one of is electrolyzer systems. Grade 26 was used selectively for low-pressure flanges, which were fabricated from about 50,000 pounds of Grade 26 plate, produced to the requirements of the project. This resulted in a significant cost saving over Ti-0.15 Pd (Grade 7) originally considered for the application. This was the first large scale application of the alloy, which is now being commercially produced as a lower cost substitute for titanium-palladium (Ti-0.15 Pd, ASTM
Grades 7 and 11) and the lean-palladium (Ti-0.05 Pd, ASTM Grades 16 and 17).
