What is the temperature range of INCONEL 800?
Introduction
INCOLOY alloys belong to the category of super austenitic stainless steels. These alloys are based on nickel-chromium-iron as base metal 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 wide range of corrosive environments.
INCOLOY alloy 800 is an alloy of nickel, iron, and chromium. The alloy is stable and maintains its austenitic structure even when exposed to elevated temperatures for extended periods of time. Other properties of the alloy include high strength and high resistance to oxidizing, reducing, and aqueous environments. Standard forms of the alloy include round bar, flat bar, forging billet, tube, plate, sheet, wire, and strip.
