Inconel 718 is a precipitation hardened 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.
At HYT, we are your direct Inconel metal supplier. We provide custom work, short lead times, and quick delivery for all types of large or small quantities of Inconel 718 shapes including tube, pipe, wire, sheet, and plate. We are also ISO Certified and provide advanced design expertise for all your Inconel 718 alloy needs.

Inconel 718 metal is commonly utilized in harsh environments where extreme heat and corrosion resistance is necessary for the success of the part or component. Inconel 718 provides the following beneficial qualities:
Excellent relaxation resistance
Can be fabricated into even the most complex parts
Offers a wide temperature range -423°F(-253°C) to 1300°F(705°C)
Outstanding tensile, fatigue, creep, and rupture strength
Gamma Prime strengthened
Excellent oxidation resistance up to 1800°F(980°C)
Available in annealed temper, aged, cold worked, or cold worked and aged
