Comparison between Inconel 600/718 round bars
Comparison between Inconel 600/718 round bars
The main difference between Inconel 600 and 718 round bars lies in their composition, which results in differences in strength, temperature resistance, and typical applications. Inconel 718 uses a nickel-cobalt matrix, offering higher strength and making it ideal for high-stress aerospace applications; while Inconel 600 is better suited for environments such as chemical plants, offering superior high-temperature resistance, oxidation resistance, and corrosion resistance.
What is the composition of Inconel 718 round bars?
Inconel 718 round bars are nickel-chromium alloy bars with a nickel content of up to 55%. Their composition includes 17% chromium, 4.9% niobium, at least 6.6% iron, and aluminum, boron, carbon, cobalt, copper, manganese, phosphorus, lead, sulfur, and silicon.
