Application
Chemical Processing: NiCrMo alloys are particularly resistant to both oxidizing and reducing acids and other corrosive media, making them ideal for chemical reactors, heat exchangers, and piping systems in chemical plants.
Oil and Gas Industry: Due to their excellent resistance to pitting, stress corrosion cracking, and crevice corrosion, these alloys are used in sour gas environments and for equipment like separators, scrubbers, and pumps in oil and gas extraction and processing.
Pollution Control Equipment: NiCrMo and NiCrMoCu alloys are used in flue gas desulfurization systems and other pollution control equipment because of their corrosion resistance to flue gases and other environmental contaminants.
Marine Engineering: The alloys’ resistance to seawater and marine conditions makes them suitable for shipping components, such as propeller shafts and pumps.
Power Generation: Their resistance to high-temperature oxidation makes these alloys suitable for parts in power plants, including boilers, cooling systems, and waste treatment systems.
Pulp and Paper Industry: NiCrMo alloys are used in equipment exposed to corrosive pulp and paper manufacturing chemicals.
Pharmaceuticals: These materials’ high purity and corrosion resistance make them suitable for pharmaceutical equipment where maintaining product purity is crucial.
Desalination Plants: NiCrMoCu and NiCrMoW alloys are often used in desalination plants to resist highly corrosive seawater environments.
