Difference Between Incoloy 800 and Inconel 800

 

Difference Between Incoloy 800 and Inconel 800

Incoloy 800 also known as Inconel 800 which is nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. The nickel content makes Incoloy800 highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties.

Incoloy 800 is mainly in demand by applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

Inconel 800 Vs Incoloy 800

The Inconel materials are used in high heat applications and food grade applications. Incoloy and Inconel are registered trademarks for nickel based superalloys. These were produced by the Special Metals Corporation and have different applications. The Inconel are nickel chromium alloys with high oxidation resistance properties. The incoloy material is mostly nickel based can perform under high temperatures as well. Their corrosion resistance is mostly against concentrated acids such as sulfuric acids. Therefore the incoloy material could be used in acid production plants and in chemical applications. The different materials have different type of mechanical properties as well.

The Inconel 800 has about 536MPa minimum tensile strength and 150MPa minimum yield strength at room temperature. The incoloy 800 has 600MPa minimum tensile strength and 275MPa minimum yield strength. The incoloy material is stronger than the icnonel and therefore it could be used in high strength applications. The elongation at break for incoloy is at 45%. The density of incoloy 800 is also high with 7.94 grams per cubic centimeter. These materials could have the additions of molybdenum, copper, silicon and nitrogen in varying quantities based on the different grades.

Both these materials are used to produce bars, rods, pipes, tubes, flanges, Fastenners, fittings and other types of products for use in different applications. These can be welded with most common welding procedures given the right filler material is used. The forming operations are easy to carry out as they posses good ductility. Hot working and cold working are possible on these materials with the standard tools. They can be heat treated and annealed to improve the hardness. The applications can also include sheathing, heating element, nuclear steam tubes, heat exchangers, boilers, super heater and in carburizing equipment.
