In regions where standard stainless steels 316 and 321 get oxidized, scaled, and carburized, Incoloy 800 flanges (UNS N08800) retain strength and sealability beyond 900 degrees Centigrade due to the composition of nickel, iron, and chromium. In applications that require flanges resistant to high temperature, such as ammonia reformers, ethylene furnaces, heat treatment furnaces, and sulfuric acid

Frequently Asked Questions
What Is Incoloy 800 Used For?
Incoloy 800 is mainly used in high-temperature, corrosive process lines, ammonia crackers where oxidation and carburization resistance matters
Is Incoloy 800 The Same As Stainless Steel 316?
No. Incoloy 800 is a nickel-iron-chromium alloy with much higher nickel content than 316 stainless
What Is The Maximum Service Temperature For Incoloy 800 Flanges?
Incoloy 800 resists oxidation, carburization and scaling up to around 1100°C (2012°F)
Is An Incoloy 800 Flange Magnetic?
It is essentially non-magnetic in the solution-annealed condition due to its high nickel-iron austenitic structure.
What Is The Difference Between Incoloy 800 And Incoloy 825?
Incoloy 800 is optimised for high-temperature oxidation and carburization resistance, while Incoloy 825 adds molybdenum and copper for stronger resistance to acidic
