ASTM B163 Incoloy 800H Nickel Alloy Tube Solution Annealed Seamless Tubing for Heat Exchangers

ASTM B163 UNS N08810 (Incoloy 800H) is a nickel‑iron‑chromium seamless alloy tube widely used for condensers, heat exchangers, and high‑temperature service. Produced strictly to ASTM B163 standard, it is supplied in solution‑annealed condition for excellent creep strength, thermal stability, and corrosion resistance.

With controlled carbon content and stabilized Al/Ti, it performs reliably at temperatures up to 800°C, resisting oxidation, carburization, and chloride stress corrosion cracking. It features good mechanical properties, uniform wall thickness, and tight dimensional tolerances.

Widely applied in petrochemical reformers, power plant heat exchangers, industrial furnace components, and high‑temperature process piping, it ensures long service life under harsh thermal and corrosive environments.

• Excellent high-temperature creep strength and rupture strength at 538℃-800℃
• Superior oxidation and carburization resistance in high-temperature flue gas environments
• High resistance to chloride stress corrosion cracking (SCC)
• Good resistance to nitric acid, organic acid, alkaline solution and mixed corrosive media
• Stable metallurgical structure, anti-thermal fatigue and long service life

• Heat exchanger tubes, condenser tubes, shell & tube heat exchangers
• Petrochemical reformer furnace coils, high-temperature heating coils
• Power plant superheater, reheater and auxiliary cooling system
• Industrial furnace radiant tubes, heat treatment furnace components
• Coal chemical, synthetic gas and high-temperature reaction pipeline systems
