Model Number: PJJ-18
Brand Name: Bozhong
Key Specifications/Special Features:
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.Other DesignationsSome of the designations used to denote INCOLOY alloy 800 are listed below:UNS N08800AMS 5766AMS 5871ASTM B163ASTM B366

FabricationMachinabilityMachining characteristics of this INCOLOY alloy 800 are similar to that of iron-based alloys. This alloy tends to work-harden during machining.
WeldingINCOLOY alloy 800 can be welded by common welding techniques, using a matching filler metal.
FormingThis alloy exhibits good ductility and hence can be formed using conventional methods.
Hot workingINCOLOY alloy 800 can be hot worked at temperature ranges of 871-1232°C (1600-2250°F).
Cold WorkingCold working may be done on the alloy using standard tooling.
AnnealingINCOLOY 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.
ApplicationsINCOLOY alloy 800 is used in the following applications:
- Heat exchangers
- Carburising equipment
- Heating elements
- Sheathing and nuclear steam generator tubing.
