Inconel 600 strip and Incoloy 800 strip are two frequently utilized nickel alloys strips. Their functionalities exhibit resemblances, with both alloys catering to diverse industrial applications.
However, across all aspects, Inconel 600 alloy strip showcases superior performance when compared to Incoloy 800 alloy strip. Conversely, Incoloy 800 boasts a more economical cost and can serve as a substitute for Inconel 600 in certain scenarios.
Determining the suitable choice for your alloy strip project can be perplexing. This article aims to delineate the disparities between these two nickel-based alloys strips, aiding you in arriving at a well-founded choice.
Let’s keep reading.
What is Inconel 600 Alloy Strip?
Inconel 600 alloy strip is a standard engineering nickel alloy strip material for applications which require resistance to corrosion and heat.
The alloy strip also has excellent mechanical properties and presents the desirable combination of high strength and good workability.
Inconel 600 strips are slitted from mother coils.

What is Incoloy 800 Alloy Strip?
Incoloy 800 strip is a nickel based alloy strip that has high resistance to oxidation and heat.
Incoloy 800 strip is a nickel-iron-chromium alloy containing 21% chromium, 32% nickel and various amounts of manganese, aluminum and titanium. In addition to its excellent corrosion resistance at high temperatures, the alloy has good resistance to stress corrosion cracking because of its high nickel content.
Incoloy 800 strip has excellent high temperature strength combined with excellent resistance to oxidation and corrosion at temperatures up to about 1,100°C (2,000°F). It also has good mechanical properties at low temperatures down to about -200°C (-328°F).
This alloy strip can be used in a variety of applications, including heat exchangers and fuel cell construction.
The typical applications for Incoloy 800 strip include high temperature tubes and parts for high pressure steam or gas pipelines, heat exchangers in nuclear power plants or chemical processing plants, superconducting magnets for MRI machines or particle accelerators, exhaust ducts for commercial airplanes and rocket engines among others.
Difference Between Inconel 600 Strip and Incoloy 800 Strip
As you can see from their introduction and products types, Inconel alloy Inconel 600 strip and Incoloy 800 strip are very different. Depending on what you are looking for in your project, they each have benefits and drawbacks. For a side by side comparison, you breakdown the differences even further.
