N08800 Nickel Alloy Tube Pipe for Industry/Aerospace

N08800 Nickel Alloy Tube Pipe For Industry/Aerospace IntroductionINCOLOY alloys belong to the category of super austenitic stainless steels. These alloys have nickel-chromium-iron as the base metals, with additives such as molybdenum, copper, nitrogen and silicon. These alloys are known for their excellent strength at elevated temperatures and good corrosion resistance in a variety of corrosive environments.INCOLOY alloy 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.This datasheet will look into the chemical composition, properties and applications of INCOLOY 800.Chemical CompositionThe chemical composition of INCOLOY alloy 800 is given in the following table.
