Corrosion Resistance of Inconel 718 Flanges

One of the most exceptional properties of Inconel 718 flanges is their corrosion resistance. These flanges offer outstanding resistance to oxidation, pitting, crevice corrosion and chloride-induced stress corrosion cracking. They are highly resistant to sulfuric acid, hydrochloric acid, and nitric acid, making them ideal for chemical processing.

Chemical Composition of Inconel 718 Flanges

The chemical composition of Inconel 718 flanges is critical to their properties and characteristics. Inconel 718 is a nickel-chromium-molybdenum alloy containing iron, niobium, titanium, and aluminium. The nickel component makes up about 50% of the alloy, while chromium constitutes about 17%. Molybdenum and niobium, on the other hand, make up around 3-5% each. Aluminium and titanium are also present in small quantities, but their impact on the alloy's properties is significant.

Machining of Inconel 718 Flanges

As an alloy known for its high strength and toughness, Inconel 718 can be challenging to machine. Machining Inconel 718 requires special considerations to achieve excellent surface finishes and dimensional accuracy without affecting the integrity of the flange. The recommended tools for machining Inconel 718 flanges are carbide-tipped and high-speed tools, and the cutting speed, feed rate, and depth of cut must be optimized to achieve the desired results while minimizing tool wear.
