Alloy 718 flat-product specification with a different solution-treatment route from AMS 5596.
Solution treated at approximately 1066 °C; confirm the ordered revision.
The reviewed scope covers sheet, strip and plate. Acceptance includes condition-specific requirements; the AMS 5596 values are not interchangeable.

Chemical & Mechanical Properties
Select a table to compare the source-labelled material data.
| Grade / identification | Ni % | Cr % | Mo % | Nb + Ta % | Ti % | Al % |
|---|---|---|---|---|---|---|
| Alloy 718 N07718 | 50.0–55.0 (including Co) | 17.0–21.0 | 2.80–3.30 | 4.75–5.50 | 0.65–1.15 | 0.20–0.80 |
Manufacturer alloy composition limits, mass %; selected elements only. These are not the complete acceptance limits of the standard on this page.
These published alloy values are comparison data. The AMS 5597 acceptance limits must be checked in the specified revision.
Alloy 718: mechanical acceptance depends on the specified solution treatment and ageing cycle. The ordered revision determines delivery and test requirements.
Typical properties are comparison values. Manufacturer limits marked “min” apply only to the stated product. Confirm the ordered revision, thickness, heat treatment, specimen direction and gauge length before material acceptance.
Engineered for demanding service.
Grade selection depends on the process environment, temperature, corrosion exposure and equipment design.
From material specification to gasket construction
Select the required product form, grade, delivery condition and certification for the approved gasket construction. Finished gasket dimensions and performance requirements are established separately.

Short answers for engineers and purchasing teams.
How should AMS 5597 be specified?
State the revision, exact material grade, product form, dimensions, delivery condition and certification requirements on the purchase order.
Are the displayed properties specification acceptance limits?
The tables identify published manufacturer reference data. Typical values describe the stated reference product and are not certified AMS 5597 limits. Use the ordered revision for material acceptance.
Are these all the materials covered by the standard?
This page links selected materials already present on the website. The linked material list is not the complete scope of the standard.
