UNS N08800, 1.4876, comparable to Incoloy 800 Alloy
UNS N08800 is a nickel-iron-chromium alloy that provides high strength and excellent resistance to oxidation and carburization at high temperatures. It also offers excellent corrosion resistance in many aqueous environments.
We have following form provide, other form could be custom producing.
Workability performance Incoloy 800 Alloy
Whether for hot working or cold working, N08800 offers workability similar to austenitic stainless steels. For hot working, temperatures should be between 1000 and 1230℃, although light work may be done at temperatures as low as 850℃. To prevent cracks, we recommend avoiding the temperature range between 650 and 800℃. Although cold workability is similar to austenitic stainless steels, work hardening tends to be slightly lower.
Weldability for the pipe Incoloy 800 Alloy
As with standard austenitic stainless steels, N08800 may be welded using techniques such as TIG, MIG, and shield metal arc welding. AWS ERNiCr-3/AWS ENiCrFe-2 welding rods are often used.
Heat Treatment around 1000 degree Incoloy 800 Alloy
N08800 exhibits an austenite structure similar to austenitic stainless steels, and appropriate heat treatment procedures and requirements are similar. Typical heat treatments are as follows:
Annealing: 980~1060℃; rapid cooling
Properties at High Temperatures for Incoloy 800 Alloy
Because of its high nickel and chromium content, N08800 resists oxidation and carburization at high temperatures. N08800 is superior to Type 310S and approaches N06600 in resistance to oxidation. Offering superior high-temperature strength nearly equal to N06600, N08800 is widely used in applications requiring heat resistance, as they do not become brittle due to sigma phase precipitation during use. While N08800 is generally used at temperatures below 600℃, 800H/800T are recommended for applications requiring superior creep properties at higher temperatures.
Corrosion Resistance in the austenitic stainless steels Incoloy 800 Alloy
N08800 offers superior corrosion resistance in oxidizing corrosive environments such as nitric acid or nitric acid-sulfuric acid. Likewise, it performs well in sodium salt and other molten salt environments, with stress corrosion cracking resistance surpassing standard austenitic stainless steels.
Applications in the industry Incoloy 800 Alloy
N08800 is widely used in sheathed heaters, thermocouple protection tubes, heat treatment furnaces, and other high-temperature environments
