Product Overview –Inconel 825 Tubes
Inconel 825 Tubes, are premium nickel-iron-chromium alloy tubes alloyed with molybdenum, copper, and titanium to provide exceptional resistance against oxidizing acids, reducing acids, chloride-containing environments, seawater, sulfuric acid, phosphoric acid, and stress corrosion cracking. Designated as UNS N08825, this alloy is engineered for industries where conventional stainless steels fail due to aggressive corrosion conditions.
The balanced alloy chemistry provides excellent resistance to pitting, crevice corrosion, intergranular corrosion, chloride stress corrosion cracking, and general corrosion while maintaining good mechanical strength over a wide temperature range.
Incoloy 825 Tubes are extensively used in chemical processing plants, offshore oil & gas platforms, marine engineering, desalination plants, pollution control systems, heat exchangers, nuclear fuel reprocessing, phosphoric acid production, sulfuric acid plants, pickling equipment, and fertilizer industries.
