English 
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 Jiangsu 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.
For more information regarding our Inconel 718 nickel-chromium alloy metals, get in touch with our sales staff or request a quote today. Jiangsu HYT is your trusted source for premium Inconel 718 nickel-chromium materials.

Inconel 718 finds extensive applications in various demanding environments due to its high-temperature strength and excellent corrosion resistance. Some of the key applications include:
Aerospace: Components for jet engines, high-speed airframe parts
Gas Turbines: Components exposed to high temperatures and corrosive environments
Nuclear Reactors: Structural components
Oil & Gas Industry: Down-hole shafting and wellhead parts
Automotive: Parts that require high strength and corrosion resistance
Plastic Injection Molding: Tools and components
High-Temperature Bolts & Fasteners
High Yield Strength: Exceptionally high yield strength.
Excellent High-Temperature Tensile & Creep Rupture Properties: Retains strength over a wide temperature range.
Excellent Weldability: Can be welded without spontaneous hardening.
Outstanding Corrosion Resistance: Highly resistant to various types of corrosion.
Does Not Spontaneously Harden: Maintains its properties during heating and cooling processes.
Jiangsu HYT offers nickel alloy Inconel 718 in a variety of forms, including:
Bar
Wire
Sheet
Plate
Forgings
Pipe fittings
Flanges
Seamless & Welded pipe
Seamless Tube & Welded tube
Weld Rod
Nickel alloy 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.
Inconel 718 strip is available from 0.001" to 0.063" in 12" wide coils. 24" wide strip is available in some gauges. Minimum production quantities may apply.
Inconel 718 sheet is available from 0.012 - 0.156" thickness in 36" & 48" wide sheets.
Inconel 718 plate is available from 0.1875" thick to 4"
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 nickel alloy Inconel 718 pipe is generally not available from stock in many cases we can have pipe sizes fabricated, machined or drawn to order.
