Product Overview –Hastelloy C276 Tubes
Hastelloy C276 Tubes, are premium nickel-molybdenum-chromium alloy tubes designed to provide exceptional corrosion resistance in some of the most demanding industrial environments. Designated as UNS N10276, this alloy offers outstanding protection against oxidizing and reducing chemicals, wet chlorine gas, chlorine dioxide, sulfuric acid, hydrochloric acid, phosphoric acid, seawater, and chloride-containing media while maintaining excellent mechanical strength and fabrication properties.
Hastelloy C276 is one of the most versatile corrosion-resistant nickel alloys available today due to its exceptional resistance to pitting, crevice corrosion, stress corrosion cracking, intergranular corrosion, and localized chemical attack The alloy also performs exceptionally well in welded conditions because of its low carbon and silicon content, reducing the risk of sensitization during fabrication.
These tubes are widely used in chemical processing plants, offshore oil & gas facilities, marine engineering, flue gas desulfurization systems, pharmaceutical plants, pulp & paper mills, pollution control equipment, heat exchangers, pressure vessels, nuclear power plants, and waste treatment facilities.
