Nickel is one of the most versatile metals with a wide range of applications in various industries such as aerospace, automobile, and manufacturing. One of the most popular nickel alloys is Inconel 718, renowned for its exceptional properties like high strength, durability, and excellent corrosion resistance.
Features of Inconel 718 Flanges
Inconel 718 flanges have a range of features, making them one of the most preferred materials for high-performance applications. These flanges can withstand extreme temperatures, making them ideal for high-temperature environments. Their high tensile strength also makes them resilient to stress and corrosion, making them suitable for harsh and corrosive environments. Inconel 718 Flanges can resist cracking and distortion and retain their strength even at elevated temperatures.

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.
