What isDifference Between Incoloy 800 and Inconel 800

 Difference Between Incoloy 800 and Inconel 800

Incoloy 800 also know Inconel 800. Its an alloy which is composed of nickel, chromium and iron with exceptional strength and resistance to oxidation and carburization in immense temperature atmosphere. The high content of nickel maintains the structure to attain the ductility in the alloy, it also furnishes the alloy against resistance to scaling, stress corrosion cracking and general corrosion. The alloy 800 is exquisite resistance to both chlorides, intergranular corrosion, stress corrosion cracking caused by sensitization.

Inconel 800 vs Incoloy 800

Incoloy 800 is an alloy with a higher content of iron. Due to the alloy having a higher content of ferrous, and lower content of nickel, the cost of Inconel 800 becomes low. And because it is an economical option, the alloy is considered to be an ideal material for applications that are involved in elevated temperature. Despite being used at an elevated temperature, the applications that use this alloy tend to be less critical ones. The alloy is relatively easy to fabricate. Thus, manufacturers may use the same machines and processes techniques that are associated with the processing of stainless steel alloys. The emphasis of this alloy is placed on the fact that it is more resistant to aggressive forms of corrosion. In particular, Incoloy 800 shows very high resistance to corrosive compounds seen in aqueous environments. The inclusion of chromium in combination with nickel in its chemistry makes it resilient to chemical and environmental corrosion. The alloy also exhibits resistance to physical deterioration, e.g. - surface pitting and cracking. Incoloy 800 is a popular choice in the oil and gas industries because it can withstand sour gas and high chloride environments. The alloy exhibits excellent resistance to seawater and brine, making it well suited to marine applications. Incoloy 800 may be also used for applications such as wet scrubbing, and the reactive atmospheres of furnaces as well as in industries like nuclear fuel.

Inconel 800, whose chemistry forms over 50% of nickel is known to be more expensive than the former. Nickel is a costly commodity, which is why its use in an alloy elevates its cost. When heated, Inconel 800 forms a thick yet stable oxide layer. This thick layer is known to protect the outer surface of the Inconel 800 component from further attack. This phenomenon is the reason why manufacturers recommend using Inconel 800 for extreme temperature and high pressure applications. In such extreme conditions, metals or alloys such as steel and aluminum would succumb to thermal creep. Typical applications of Inconel 800 include the food and beverage industry, in addition to being used for heat treatment components. Due to its high strength and stiffness properties, Inconel 800 is an alloy that is ideal for demanding applications including the marine engineering, aerospace, and chemical processing industries.
