Here's a professional English product introduction for UNS N08810 (Incoloy 800H/HT):

‌UNS N08810‌ is a nickel-iron-chromium alloy designed for exceptional performance in high-temperature and corrosive environments. With its balanced composition of 30-35% nickel and 19-23% chromium, it offers superior oxidation resistance and mechanical strength.

‌Key Characteristics:‌

• Excellent resistance to oxidation and carburization at temperatures up to 1177°C
• Maintains high tensile strength (≥450MPa) and good ductility (≥30% elongation) at room temperature
• Outstanding corrosion resistance in sulfuric, phosphoric, and nitric acids
• Good resistance to chloride-ion stress corrosion cracking
• Stable mechanical properties in both cryogenic and high-temperature conditions

‌Primary Applications:‌
• Petrochemical Industry: Cracked gas furnace tubes, reforming furnace components
• Power Generation: Boiler superheaters, reheater tubes in thermal power plants
• Nuclear Energy: Reactor pressure vessels and piping systems

• Aerospace: Jet engine components and combustion chambers
• Marine Engineering: Seawater cooling systems and offshore platform equipment

The material is available in various forms including plates, tubes, and bars, complying with standards such as ASTM B407. Its unique combination of high-temperature strength and corrosion resistance makes N08810 particularly suitable for extreme service conditions.
