What is the difference between Inconel Alloy 600 and Inconel Alloy 601?

Alloy 600 is normally paramagnetic at room temperature; however, it becomes ferromagnetic at grain boundaries where it is depleted of chromium. This suggests that Alloy 600 can be used for magnetically sensitized nondestructive testing (NDE).

Both alloys have good high temperature properties. Among them, Inconel 601 alloy adds more chromium on the basis of Inconel 600 alloy. Therefore, the main difference between them is the difference in oxidation resistance.

Inconel 600 and Incoloy 800 are both high-performance nickel-based alloys, but their main difference is in their composition and therefore their properties. Inconel 600 is a nickel-chromium alloy known for its high strength and corrosion resistance, while Incoloy 800 is a nickel-iron-chromium alloy designed for high-temperature applications. Incoloy 800 generally has a lower nickel content and a higher iron content than Inconel 600.

Monel 400 is a nickel-copper alloy. It has excellent corrosion resistance in flowing seawater and is suitable for room temperature corrosion applications. Inconel 600 is a nickel-chromium-iron alloy that is mainly used for high temperature corrosion applications.
