ASTM B163 UNS N08810 Incoloy 800H Seamless Bright Annealed Nickel Alloy Tube For Condenser
ASTM B163 UNS N08810 Incoloy 800H Seamless Bright Annealed Nickel Alloy Tube For Condenser
ASTM B163 UNS N08810 Seamless Nickel Alloy Tubes are applied for high-temperature and corrosion-resistant applications, widely used in petrochemical, nuclear power, and aerospace Industries Where Extreme Thermal Stability and Oxidation Resistance Are Critical. Its Excellent creep strength and microstructural stability at elevated temperatures make it ideal for heat exchangers, Superheater tubes, and reactor components. The tube’s nominal diameter typically ranges from 6.35 mm to 88.9 mm. The delivery condition of Incoloy 800H tubes can be straight tubes or U bend tubes. YUHONG GROUP has manufactured nickel alloy tubes for 35 years and has abundant exporting experience to 85 countries worldwide. All nickel alloy tubes are passed through strict inspection before shipment.
