Incoloy 800 (Alloy 800, UNS N08800) Foil for Sale

Product Information

Incoloy alloy is also a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications that require high corrosion resistance and high-temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications. Incoloy products are mostly chromium-based and mostly nickel-based, and designed for corrosion resistance as well as strength at high temperatures. Incoloy alloys belong to the category of super austenitic stainless steels. One advantage is that Incoloy alloys do not have to be heat treated after welding to restore the corrosion resistance. There are specific alloys for resistance to particular chemical attacks. For example, alloy 020 is designed to be resistant to sulphuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles.Alloy 800 is a widely used material of construction for equipment that must resist corrosion, have high strength, or resist oxidation, carburization, and other harmful effects of high-temperature exposure. The Chromium in the alloy imparts resistance to oxidation and corrosion. The high Nickel content maintains an austenitic structure so that the alloy is ductile. The Nickel also contributes resistance to scaling, general corrosion, and stress corrosion cracking. The iron content provides resistance to internal oxidation.

Applications of Incoloy 800 Foil

Due to high strength during long periods of service and resistance to carburization and nitridation, ALLOY800 have found many applications in steam/hydrocarbon reforming for components such as: pigtails, headers/collectors/manifolds, transfer piping, catalyst tubes (in lowpressure processes) and quench-system piping.

Typical applications are:

• ethylene pyrolysis tubing in convection and radiant sections – resistance to carburization and good mechanical properties

• ethylene dichloride cracking tubes ? resistance to carburization and to dry hydrogen chloride and chlorine

• cracking tubes used in the production of acetic anhydride and ketene – high strength, resistance to both carburization and the formation of sigma phase

• components, e.g. heat exchangers, piping systems etc., in coal conversion plants

• steam generator tubing in helium cooled, high temperature reactor systems ? high strength, resistance to helium and to steam

Packing of Incoloy 800 Foil

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’ Incoloy 800 Foil is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.

Inconel Alloys Include

Incoloy refers to a range of superalloys now produced by the Special Metals Corporation (SMC) group of companies and created with a trademark by the Inco company in 1952. Originally Inco protected these alloys by patent. In 2000, the SMC published a 61-page document entitled "High-Performance Alloys for Resistance to Aqueous Corrosion" highlighting Incoloy, as well as Monel and Inconel products, and their use in fluid environments such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, nitric acid, other acids as well as freshwater environments.

Incoloy products are mostly chromium-based and mostly nickel-based, and designed for corrosion resistance as well as strength at high temperatures.

Incoloy alloys belong to the category of super austenitic stainless steels. One advantage is that Incoloy alloys do not have to be heat treated after welding to restore the corrosion resistance.

There are specific alloys for resistance to particular chemical attacks. For example, alloy 020 is designed to be resistant to sulphuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles.

Incoloy 020 "exhibits excellent corrosion resistance in chemical environments that contain sulphuric acid, chlorides, phosphoric acid and nitric acid."

Incoloy 028 "is resistant to both acids and salts. The copper content makes it resistant to sulfuric acid."

Incoloy 330 "exhibits good strength at high temperatures and good resistance to oxidation and reduction environments."

Incoloy 800 "is capable of remaining stable and maintaining its austenitic structure even after long time exposures to high temperatures".

Incoloy 803 is designed for sulphur-rich environments.

Incoloy 825 is approved for use in heat exchanger tubes by ASTM B163, and approved for pressure vessel operating temperatures up to 525°C or up to 538°C. It "offers exceptional resistance to corrosion by sulphuric acid and phosphoric acid".

Incoloy 908 "has high tensile strength, fatigue crack growth resistance, good weldability, metallurgical stability and ductility, high fracture and impact toughness, [and] low coefficient of thermal expansion... [Its] resistance to oxygen embrittlement... allows hot fabrication without cracking."

Incoloy 907 "has high strength and low thermal expansion coefficient at temperatures up to 800°F."

Incoloy 945X is designed for chlorine-rich environments. Molybdenum adds crevice corrosion and pitting resistance to Incoloy 945.

Incoloy MA956 is made by a mechanical alloying rather than a bulk-melting process; it was studied for space reactor components in the JIMO project. It is difficult to weld and needs to be heated to 200C for forming processes. A special friction welding process has been developed for it.
