Hastelloy C-22

C-22 has outstanding resistance to both reducing and oxidizing media and because of its resistibility can be used where "upset" conditions are likely to occur. It is proven to possess excellent weldability and high corrosion resistance as consumable filler wires and electrodes. The alloy has proven results as a filler wire in many applications. As filler wire use when other corrosion resistant wires have failed.

C-22 can easily be cold-worked because of its ductility and cold-forming is the preferred method of forming. More energy is required because the alloy is generally stiffer than austenitic stainless steels.

Applications:

- Chlorination systems

- Flue gas scrubbers

- Outlet ducting and stack liners for power plants, pulp and paper bleach plants, sulfur dioxide scrubbers, and weld overlay of less corrosion resistant metals

- Acid production and pickling systems
