Product Description
DLX Alloy's Inconel 625 (UNS N06625 / W.Nr. 2.4856) sheet and plate is a high-performance nickel-chromium-molybdenum alloy engineered for extreme environments in the hydrogen energy sector. With outstanding corrosion resistance and mechanical strength from cryogenic temperatures up to 980°C (1800°F), Inconel 625 is the preferred material for manufacturing hydrogen storage tanks, high-pressure gaseous hydrogen cylinders, liquid hydrogen vessels, and hydrogen transportation pipelines/trailers. It delivers superior resistance to hydrogen-induced cracking and embrittlement, ensuring long-term safety and reliability in clean energy applications.
Our Reliable Inconel 625 Sheet/Plate stands out with its robust features tailored for the petrochemical industry:
Minimal susceptibility to hydrogen-induced cracking even at high pressures (up to 700+ bar) and across wide temperature ranges.
Resists pitting, crevice corrosion, intergranular attack, and stress corrosion cracking in wet H2S, chloride, or acidic conditions often encountered in hydrogen production/storage.
Yield strength > 415 MPa (60 ksi), tensile strength > 830 MPa (120 ksi), maintains properties from -196°C (cryogenic LH2) to 980°C.
Ideal for high-temperature hydrogen reforming or fuel cell components.
Easily formed, rolled, and welded (GTAW/TIG recommended) with matching ERNiCrMo-3 filler.
Reduces hydrogen leakage in long-term storage applications.

Application Field
High-pressure gaseous hydrogen storage tanks (350–700 bar)
Cryogenic liquid hydrogen (LH2) storage vessels and tank liners
Mobile hydrogen tube trailers and transportation modules
Stationary hydrogen refueling station pressure vessels
Hydrogen pipeline components and valves
Fuel cell vehicle (FCV) on-board storage systems
Green hydrogen production (electrolysis) equipment exposed to pure hydrogen
Solid-state or metal hydride hydrogen storage system structural parts (combined with Inconel 718 where higher strength is needed)
DLX Alloy also recommends Inconel 718 (UNS N07718) plates for applications requiring even higher mechanical strength at elevated temperatures, while Inconel 625 remains the top choice for maximum corrosion protection in hydrogen environments.
