Inconel 718 Flanges

Common Trade Names: Inconel 718®, Nicrofer® 5219, Alvac® 718, Haynes® 718, Altemp® 718

Calico Metal Ind Pvt Ltd is involved in providing an extensive range of Alloy 718 Flanges as an exporter, manufacturer and supplier. Alloy 718 (UNS N07718) has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. It is extremely resistance to stress corrosion cracking and pitting ability in high temperature or low temperature environments, especially the inoxidability in the high temperature. Its welding characteristics, especially its resistance to postweld cracking, are outstanding. Inconel 718 is an age-hardenable Nickel-Chromium-Columbium (Niobium)-Molybdenum alloy with high strength, corrosion-resistance, and good fabrication characteristics.

In order to make sure quality, the entire range of these flanges is scrupulously tested on different parameters by quality examiners. We offer these products in different sizes, specifications and shapes as per demands of our esteemed customers. We Export Inconel 718 Flanges in Qatar, Kingdom Of Bahrain, Saudi Arabia, Indonesia, United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, Australia, etc.

Inconel 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F (704°C). The age-hardening response of Inconel 718 permits annealing and welding without spontaneous hardening during heating and cooling. Nickel Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Nickel Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Fabrication and Heat Treatment

Inconel 718 can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-base coolants. Inconel 718 is welded using gas-tungsten arc welding, shielded metal-arc welding, gas metal-arc welding, and submerged-arc welding methods.
