ASME SB163 N08810 Nickel Alloy Seamless Tubes For High Temperature And Pressure Service
YUHONG Group can offer ASTM B163 / ASME SB163 N08810 SMLS nickel alloy tubes.
ASTM B163 This specification covers seamless tubes of nickel and nickel alloys, for use in condenser, heat-exchanger and other industrial service. ASME SB163 N08810 (Alloy 800H) seamless tubes are engineered for high-temperature and high-pressure service where resistance to oxidation, carburization, and creep rupture is the primary requirement.
Below are advantages of material N08810:
1.High-Temperature Strength
2.Resistance to High-Temperature Corrosion
Oxidation Resistance: The high chromium content (19-23%) forms a stable, protective chromium oxide (Cr₂O₃) scale that resists spalling and protects the base metal from further oxidation in air or steam.Carburization Resistance: Resists the absorption of carbon in hydrocarbon-rich, high-temperature environments (e.g., furnace tubes), which can cause embrittlement and failure in other alloys.Sulfidation Resistance: Moderate resistance to sulfur-bearing atmospheres.
3.Stability in Petrochemical Processes and Good Microstructural Stability
