Chemical & Mechanical Properties
Select a table to compare the source-labelled material data.
| Grade / identification | Ni % | Cr % | Mo % | Nb + Ta % | C % |
|---|---|---|---|---|---|
| Alloy 625 N06625 | 58.0 min | 20.0–23.0 | 8.0–10.0 | 3.15–4.15 | 0.10 max |
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 5599 acceptance limits must be checked in the specified revision.
| Grade / identification | Product form / condition | Tensile (MPa) | 0.2% proof / yield (MPa) | Elongation (%) | Data basis |
|---|---|---|---|---|---|
| Alloy 625 N06625 | Annealed sheet / strip; room temperature | 827–1034 | 414–621 | 30–55 | Manufacturer nominal ranges, not AMS acceptance values. |
| Alloy 625 N06625 | Solution-treated plate (manufacturer groups rod, bar and plate); room temperature | 724–896 | 290–414 | 40–65 | Manufacturer nominal ranges; applies to stated condition only. |
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 5599 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 5599 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.
