Nickel-based alloys possess high alloy content, such as Cr, Ni, Mo, etc., and maintain excellent overall performance in high-temperature and highly corrosive environments. For example: strong resistance to acid and alkali corrosion; excellent high-temperature corrosion and stress corrosion resistance; some also exhibit good corrosion resistance in both reducing and oxidizing media. They are widely used in flue gas desulfurization equipment for thermal power generation, wastewater treatment; chemical, petrochemical, and marine development industries for the production of chemicals with strong media corrosion and harsh environments, manufacturing of heaters, heat exchangers, evaporators, condensers, and pipelines; in the energy sector for nuclear power generation, comprehensive utilization of coal, tidal power generation; marine structures in oceanic environments, seawater desalination, aquaculture, seawater heat exchange; in the food industry for salt production, soy sauce brewing, etc.
