CD4MCU duplex stainless steel forgings

Ring forgings: Widely used in marine engineering (such as propeller shaft collars and seawater desalination equipment), chemical processing (reactor flange rings), and nuclear industry piping systems. Designed to withstand highly corrosive environments involving seawater, salt spray, and aggressive acid-alkali media.

Free forgings: Applied in the manufacture of heavy-duty, corrosion-resistant components, including high-pressure vessels in the chemical industry, bleaching equipment cylinders in the paper industry, and structural fasteners in coastal infrastructure.
CD4MCu offers excellent resistance to chloride-induced corrosion and delivers significantly longer service life than conventional austenitic stainless steels such as F304 in high-temperature, high-humidity environments.
