UNS N08811 is a nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature exposure.Incoloy 800H/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase.
UNS N08811 Nickel alloy similar material are :Incoloy 800HT,W.Nr.1.4959,X 8 NiCrAlTi 32-21
UNS N08811 Nickel alloy usually used in the following industries :
Ethylene furnace quench boilers
Hydrocarbon cracking
Valves, fittings and other components exposed to corrosive attack from 1100-1800° F
Industrial furnaces
Heat-treating equipment
Chemical and petrochemical processing
Super-heater and re-heaters in power plants
Pressure vessels
Heat exchangers
