Incoloy 800 vs Inconel 800: what’s the difference?

What Makes one Different From the Other?

Inconel and Incoloy both belong to the same family of super-alloys and are often referred to as high-performance alloys. These super-alloys are both highly resistant to oxidation and corrosion in addition to having a great deal of oxidation resistance. The mechanical properties of both super-alloys are extremely high, and their thermal stability is excellent. Both alloys are characterized by these elements, which help them perform well. The variations in their makeup distinguish them from one another since they are members of the same family. The composition of Inconel 800 and Incoloy 800 Pipes is where there is the most significant difference. As with most alloys, Inconel 800 is primarily composed of nickel and chromium.

More than 50% of nickel is commonly present in this alloy. As opposed to Incoloy 800 pipes, which are formed primarily of nickel, iron, and chromium, Nickel is the main component of Incoloy 800 pipes. Chemical composition of less than 50% nickel is present in this alloy, as opposed to the former. Besides their chemical composition, what separates each alloy is how it is used in a particular application or industry.

Two alloys, Inconel 800 and Incoloy 800 pipes are utilized for numerous purposes. Although the characteristics of the two alloys are relatively similar, there are certain distinctions between them that may make one of them better suited for a given application than the other. For instance, Incoloy 800 pipes are frequently utilized when high strength is not required, but Inconel 800 is frequently used as part of components that will be exposed to high temperatures or corrosive conditions.

Some Differences Between These Two Alloys

  • Inconel 800 is more resistant to high temperatures than Incoloy 800 because it has a higher melting point. Due to this, it is more suited for applications requiring heat resistance, such as pressure vessels, boilers, and engine parts.
  • Incoloy 800 pipes have a lower melting point than Inconel 800, allowing it to flow more readily during cooling processes, making them more suited for applications like gears and shafts where great strength is not necessary.

Inconel 800 can be made by rolling or extrusion, but it must first be shaped using hydroforming or forging techniques.
