Alloy 800H UNS N08810: Complete Guide to Properties and Applications
Alloy 800H UNS N08810 is a nickel-iron-chromium superalloy renowned for its exceptional high-temperature strength and corrosion resistance. This comprehensive guide explores its key characteristics and industrial uses, helping engineers and manufacturers select the right material for demanding environments.
Key Properties and Composition
The alloy’s outstanding performance stems from its balanced composition. With approximately 30-35% nickel, 19-23% chromium, and controlled carbon content, it maintains structural integrity under extreme thermal and mechanical stress.
High-Temperature Performance
Alloy 800H demonstrates remarkable creep and rupture strength at temperatures exceeding 1500°F (815°C). Its stable austenitic structure prevents embrittlement during prolonged exposure to heat, making it ideal for furnace components and heat treatment equipment.
Industrial Applications
This versatile material serves critical functions across multiple sectors. From petrochemical processing to power generation systems, manufacturers rely on its consistent performance in aggressive environments.
Chemical Processing Equipment
The alloy’s resistance to oxidation and carburization makes it perfect for reactor vessels, heat exchangers, and piping systems handling corrosive media at elevated temperatures.
Frequently Asked Questions
What distinguishes Alloy 800H from standard Alloy 800?
The “H” variant features higher carbon content and specific heat treatment for enhanced creep rupture properties at high temperatures.
Can it withstand sulfur-containing environments?
Yes, its chromium content provides excellent resistance to sulfidation, particularly in refinery and pyrolysis applications.
