Inconel 718 Flanges

UNS N07718 Flange, DIN 2.4668 Flanges

We are Manufacturer, Supplier & Exporter of Inconel 718 Flanges for Critical Applications, We have stock even odd sizes & hard to find flanges in high nickel alloy . We manufacture Inconel 718 Blind Flanges, Inconel 718 WNRF Flanges, Inconel 718 Orifice Flanges, Inconel 718 Threaded Flanges, Inconel 718 Slip On Flanges, Inconel 718 Reducing Flanges, Inconel 718 Socket Weld Flanges, Inconel 718 Lap Joint Flanges & all shapes & size in high nickel alloy material. Our Inconel 718 Flanges are as per ASME B16.9, ASME B16.28. standards. One of the distinguishing features of Inconel 718 Pipe Flange’s (UNS N07718) composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. Inconel 718 Slip On Flanges is used for aerospace, gas turbines, rocket motors, spacecraft, space shuttles, nuclear reactors, pumps, turbo pump seals, and tooling. Alloy 718 (UNS N07718) has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium.

It has excellent resistance to stress corrosion cracking and pitting in both high and low temperature conditions, particularly in high temperature. Its welding capabilities, particularly its resistance to postweld cracking, are exceptional. We take great pride in introducing ourselves as the most popular manufacturer of Inconel flanges. We have an ability to offer a wide range of materials such as Inconel 718 slip on flanges, Inconel 718 forged flanges and Inconel 718 long weld neck flanges that suit your needs. Inconel 718 Plate Flanges is used in heat treat furnace fixtures and components such as muffles, annealing tubes, and flame shields.
