C-276
Maximum service
temperature 1000°F (538°C) in
oxidizing and reducing atmospheres.
Excellent resistance to corrosion in
aqueous chemical process
applications including ferric, and
cupric chlorides, sea water and brine
solutions, chlorine, formic and acetic
acids, wet chlorine gas, hypochlorite
chlorine dioxide. It is also frequently
used in flue gas desulphurization
systems, since it has excellent
resistance to sulfur and chloride
ions.
