English 
INCOLOY 800 is an alloy of nickel, iron and chromium. The alloy is capable of remaining stable and maintaining its austenitic structure even after long time exposures to high temperatures. Other characteristics of the alloy are good strength, and high resistance to oxidizing, reducing and aqueous environments. The standard forms in which this alloy is available are round, flats, forging stock, tube, plate, sheet, wire and strip.

High Temperature Strength:
Incoloy 800 maintains a stable structure, even when exposed to high temperatures, up to about 1100°F (593°C). This makes it suitable for use in equipment like heat exchangers, where high temperature resistance is crucial.
Excellent Resistance to Oxidation and Carburization:
At high temperatures, Incoloy 800 resists oxidation and carburization, a form of corrosion that occurs in carbon-rich environments. This resistance is crucial for maintaining the integrity and longevity of components in chemical and petrochemical processing.
Corrosion Resistance:
Incoloy 800 offers good resistance to many corrosive media, including sulfur-containing atmospheres and various acidic conditions. This makes it an excellent choice for use in environments where exposure to such media is common, like processing units for organic acids and other chemicals.
Good Creep-Rupture Properties:
Although Incoloy 800 is not as optimized for creep and rupture resistance as Incoloy 800H or 800HT, it still offers sufficient performance for many high-temperature applications, ensuring long-term reliability and durability.
Weldability:
This alloy is relatively easy to fabricate and weld using conventional welding techniques, which simplifies manufacturing and repairs and allows for the design of complex assemblies without compromising structural integrity.
Stable Chemical Composition:
The balanced chemical composition of Incoloy 800 helps in achieving consistent properties across various sections and batches, ensuring predictable performance and quality.
