Product Description
DLX Alloy's Inconel 625 (UNS N06625) foil and strip are nickel-chromium-molybdenum superalloys designed specifically for demanding hydrogen energy applications. Thanks to its high nickel content (>58%) and additions of niobium, Inconel 625 delivers exceptional resistance to hydrogen embrittlement even under ultra-high hydrogen pressures (up to 700-1000 bar) and across wide temperature ranges (-196°C to 980°C).
Our ultra-thin Inconel 625 foil (0.01mm–0.2mm) is perfect as a barrier layer or liner in composite high-pressure hydrogen storage tanks, preventing hydrogen permeation and embrittlement of carbon fiber structures. The wider Inconel 625 strip (thickness 0.1mm–3.0mm) is widely used for welded tank components, accumulators, and hydrogen pipeline reinforcements.
All products are supplied in annealed condition for optimal formability and hydrogen compatibility, meeting ASTM B443, AMS 5599, and ASME SB-443 standards.
Nickel-chromium-molybdenum alloy: Alloy 625 combines nickel, chromium, molybdenum and niobium within specification limits.
Corrosion resistance: Used in a range of corrosive environments, including selected seawater and chemical-processing applications. Confirm suitability for the specific medium, temperature and exposure conditions.
High strength: Required mechanical properties depend on product form, thickness, supply condition and applicable specification.
Fabricability: Alloy 625 can be fabricated and joined using suitable procedures for the selected product and application.
No precipitation-hardening treatment required for basic strengthening: Confirm the required condition and properties for the material being purchased.

FAQ
No precipitation-hardening treatment is required for the basic strengthening response of Alloy 625. Confirm the required condition and mechanical properties against the applicable product specification.
The grade name alone does not establish suitability for a particular hydrogen pressure or service environment. Hydrogen compatibility depends on material condition, stress, temperature, pressure cycles, component design and relevant testing. Provide the service requirements for review.
This product listing does not qualify the foil for a particular tank design, pressure rating or hydrogen-permeation limit. Confirm suitability through application-specific engineering review and test data before specifying it as a liner or barrier.
Available dimensions depend on whether you need foil or strip and on current production capability. Send your required thickness, width, tolerance and quantity for confirmation.
