Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures. This nickel alloy is used from cryogenic temperatures up to long term service at 1200° F. One of the distinguishing features of Inconel 718's composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. The addition of niobium acts with the molybdenum to stiffen the alloy's matrix and provide high strength without a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.
In what forms is Inconel 718 Available at Metal Ministry Inc.?
What are the characteristics of Inconel 718?
- Good mechanical properties – tensile, fatigue and creep-rupture
- Yield tensile strength, creep, and rupture strength properties are exceedingly high
- Highly resistant to chloride and sulfide stress corrosion cracking
- Resistant to aqueous corrosion and chloride ion stress corrosion cracking
- High temperature resistant
- Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.
- Excellent welding characteristics, resistant to postweld age cracking
Alloy 718 (UNS N07718, W Nr 2.4668) is an austenitic nickel-based superalloy. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. Alloy 718 is used in applications that require high strength such as parts for jet engines and high speed airframe parts such as wheels, buckets, spacers and high temperature bolts and fasteners.

Typical Mechanical Properties
There are two main types of solution annealed and aging treatments:
1) Solution Treatment (AMS 5662 Bar / AMS 5596 Sheet): 1725°F - 1850°F + Air Cool. Heat Treatment (AMS 5663 Bar) : 1325°F for 8 hrs, cooling 100°F/hr to 1150°F, hold at 1150°F for 8hrs min, + Air Cool.
This treatment gives the highest room temperature tensile and yield strengths as well as producing the highest fatigue strength. It is the optimum heat treatment for Alloy 718 where a combination of rupture life, notch rupture life and rupture ductility is required.
2) Alternative Solution Treatment (AMS 5664 Bar / AMS 5597 Sheet): 1900°F - 1950°F + Air Cool Heat Treatment: 1400°F for 10hrs, furnace cool to 1200°F, hold at 1200°F for a total aging time of 20 hrs + Air Cool.
This is the prefered treatment in tensile-limited applications as it produces the best transverse ductility in heavy sections, impact strength and low temperature notch tensile strength. However, this treatment has a tendency to produce notch brittleness in stress rupture.
