INCONEL® is widely used in pollution control and waste processing, where driving demand has brought about a need for high-performance alloy materials that can withstand hazardous waste management and aggressively corrosive environments.

Superior resistance

INCONEL® alloy 625 offers high strength, excellent fabricability and has superior resistance to a wide range of corrosive environments of unusual severity, including high-temperature effects, such as oxidation and carburisation. It is also resistant to pitting and crevice corrosion.

INCONEL® alloy C-276 is also corrosion resistant in a wide range of severe environments. The high molybdenum content makes the alloy especially resistant to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. It is commonly used in pollution control, chemical processing, pulp and paper production, and waste treatment.

Acid environments

INCONEL® alloy 622 gives excellent resistance to both oxidising and reducing acid environments, as well as those containing mixed acids. It is resistant to pitting and crevice corrosion in acid-halide environments. This versatile alloy is found in chemical processing, pollution control, fluegas desulfurisation, waste incineration, and pulp and paper processing industries.

INCONEL ® alloy 625 and INCONEL® alloy 622 are also deployed in chlorine injection systems for waste water streams, whilst supercritical water oxidation technology has adopted INCONEL® alloy 625 as a preferred material in reaction chambers. They are are used for gas cleaning components, slurry systems and exit ducts.
