Product Description
Introduction
INCOLOY 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.

Fabrication
Machinability
Machining characteristics of this INCOLOY alloy 800 are similar to that of iron-based alloys. This alloy tends to work-harden during machining.
Welding
INCOLOY alloy 800 can be welded by common welding techniques, using a matching filler metal.
Forming
This alloy exhibits good ductility and hence can be formed using conventional methods.
Hot working
INCOLOY alloy 800 can be hot worked at temperature ranges of 871-1232°C (1600-2250°F).
Cold Working
Cold working may be done on the alloy using standard tooling.
Annealing
INCOLOY alloy 800 may be annealed after cold working. Annealing should be done at 982°C (1800°F) for 15 min and then the alloy should be air cooled.
