1. What is UNS N08810?

UNS N08810is a nickel-iron-chromium alloy with approximately 30-35% nickel, 19-23% chromium, and balance iron, designed for high-temperature strength and resistance to oxidation and carburization. Its controlled carbon content and grain size make UNS N08810 material ideal for furnace tubes, heat exchangers, and petrochemical equipment. Compared to UNS N08811, UNS N08810 offers similar performance but is optimized for lower temperature ranges with better creep resistance.

Gangsteel’s UNS N08810 alloy steel plate is tailored for high-temperature industrial applications, providing a robust alternative to nickel alloy steel grades like UNS N06690 and UNS N08028.
