Inconel 718 Tube

Inconel Alloy 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 degree (704 centigrade). The age-hardening response of Alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Inconel 718 is usually provided in the solution annealed condition (AMS 5662 & AMS 5596), but can be also be supplied in the aged hardened or precipitation heat treated condition (AMS 5663 & AMS 5597) prior to forming.

Size: OD 1/8''-10'', wall thickness Sch5s-XXS

Standard: SAE AMS 5589, SAE AMS 5590, DIN 17751

Inconel 718 tube is available in seamless and welded construction. Standard tube sizes are available, but we also can have small diameter tubes fabricated or re-drawn with close tolerances in small production runs.

While Inconel 718 pipe is generally not available from stock in many cases we can have pipe sizes fabricated, machined or drawn to order.
