Difference Between Incoloy 800 and Inconel 600

Incoloy 800 and Inconel 600

Incoloy 800 and Inconel 600 are two commonly used alloy materials. Both alloys have a wide range of applications and can be used in a variety of industries. But how do you know which one is right for your project? This blog post will compare the properties of these two alloys to help you make an informed decision.

Incoloy 800 vs Inconel 600

Chemical Composition

The first thing to consider when comparing any two materials is their chemical composition. Incoloy 800 has a higher chromium content than Inconel 600 and also contains nickel, copper, titanium, aluminum, and iron. Inconel 600 has a higher nickel content than Incoloy 800 but also contains chromium, titanium, molybdenum, aluminum, silicon, manganese, and iron.

Mechanical Properties

Incoloy 800 is known for its excellent mechanical properties, such as a high strength-to-weight ratio and good ductility. Additionally, it has good resistance to oxidation at high temperatures up to 1400°F (760°C). Inconel 600 also offers excellent mechanical properties such as good tensile strength, creep rupture strength at elevated temperatures up to 2000°F (1095°C), and excellent ductility in both hot and cold conditions.

Corrosion Resistance

Incoloy 800 offers superior corrosion resistance against organic acids such as formic acid or acetic acid, as well as chloride-containing environments like seawater or brackish water. On the other hand, Inconel 600 offers superior corrosion resistance against reducing acids such as sulfuric or phosphoric acid, as well as environments containing high concentrations of chlorides or halides.


After comparing the various properties of these two alloys, it is clear that each one has its own advantages, depending on your application needs. For instance, if you need superior corrosion resistance against reducing acids, then Inconel 600 would be the ideal choice, whereas if you need excellent mechanical properties, then Incoloy 800 would be better suited for your application requirements. It is important to evaluate your specific application needs before selecting either alloy material so that you get the most out of your investment!
