Leading Forging Suppliers for Inconel 718 & 625
We focus on the two most critical alloys in the superalloy market, ensuring our grain flow and thermal
processing meet the most stringent aerospace and energy standards.
Inconel 718 Forging (AMS 5662 / 5663)
Inconel 718 is the “workhorse” of the industry. Inconel 718 is an age-hardenable nickel-based superalloy selected
for its high strength, fatigue resistance, and useful mechanical
performance at elevated temperatures. Depending on the required
material condition, forged 718 may be supplied to specifications
such as AMS 5662 or AMS 5663.
Typical room-temperature reference yield strength for
precipitation-hardened material can be approximately
1,035 MPa (150 ksi), depending on product form,
section size, heat treatment, and governing specification.
Inconel 625 Forging (AMS 5666 / ASTM B564)
For environments where corrosion resistance is more critical than pure tensile strength,
our Inconel 625 forgings provide superior protection against pitting and crevice corrosion.
