Inconel 718 Bar

Inconel Alloy 718 - AMS 5662, AMS 5663 Inconel 718 Bars For Sale

Every type of steel that is used in the most rigorous of industries has its own properties and are treated in varying ways to provide the appropriate amount of resilience needed for the processes in which it will be used.  A common alloy used in the aerospace industry is Inconel 718 bar. Inconel is a high-strength nickel alloy that can stand up to extremely high temperatures, up to 1300 degrees Fahrenheit, while maintaining its appropriate mechanical properties yet Inconel 718 bar is still suitable for welding and other processes that require formability.

In terms of Aerospace Material Specifications (AMS), AMS 5662 material is precipitation hardenable solution treated bars, forgings and rings.  AMS 5663 is solution treated and aged for bars, forgings and rings.  For versatility purposes, Inconel 718 is often ordered to AMS 5662 standards with the capability of then being aged to AMS 5663 standards.


Description: Alloy 718 is a high strength specialty steel grade that can withstand high tensile, yield and creep-rupture properties up to 1300o F. Inconel / nickel 718 is a precipitation hardening  alloy that is capable of age hardening through the appropriate heat treatment procedures. Compared to most other nickel alloys, 718 has good weldability and formability. 718 can be welded in either the annealed, AMS 5662, or aged condition, AMS 5663. If completed in the age hardened condition, AMS 5663, there will be a softened heat-effected zone. 718 is non-magnetic and has good corrosion and oxidation resistance. 

Common Applications: Gas turbine engines, cryogenic tanks, motor components, springs and fasteners etc.
