Jade Alloys supplies ASTM B443 / AMS 5599 Inconel 625 Sheets and Plates from stock in Mumbai, available in thicknesses from 0.3 mm to 120 mm, with same-week dispatch to global buyers in over 50 countries. Also referred to as Nickel Alloy 625, this superalloy is valued for its high strength and ability to perform in corrosive and high-temperature conditions. Every product complies with ASTM B443 / AMS 5599 standards and is backed by Mill Test Certificates for international quality assurance.
The Inconel 625 Plate is a nickel-chromium alloy strengthened with molybdenum and niobium, manufactured in our Mumbai plant. This composition delivers excellent strength without precipitation-hardening treatment, and provides outstanding resistance to a wide range of corrosive media and high-temperature conditions including oxidation and carburization. The material offers high tensile, creep and rupture strength along with high fatigue and thermal-fatigue strength, making the Alloy 625 Sheet and Plate ideal for demanding applications. These products operate across a constant service temperature range from cryogenic conditions up to 1093 degrees C (2000 F).
The exceptional corrosion resistance of Alloy 625 sheet in saline and seawater environments, attributed to its high nickel content, makes it invaluable for marine and offshore oil drilling applications. The ASTM B443 UNS N06625 sheets are also widely used in seawater processing plants, flare stacks, aircraft components, and chemical processing facilities. Inconel 625 coils are frequently used in heat exchangers and condensers due to their outstanding heat resistance.
We supply these materials in various finishes including Hairline and Mirror, and offer custom lengths or cut-to-size options to meet specific project needs. Our product line includes both cold-rolled and hot-rolled varieties such as Alloy 625 plate and clad plates. Our competitive pricing for Inconel sheets and plates makes us a preferred choice for clients worldwide.

Inconel 625 Sheets and Plates Chemical Composition
The exceptional corrosion resistance and high strength of Inconel 625 come from its specific blend of alloying elements, with nickel, chromium, molybdenum and niobium being the primary constituents.
| Grade | C | Mn | Si | Cu | S | Fe | Mo | Nb | Ni |
|---|---|---|---|---|---|---|---|---|---|
| Inconel 625 | 0.10 max | 0.50 max | 0.50 max | 0.40 max | 0.015 max | 5.0 max | 8.0 to 10.0 | 3.15 to 4.15 | 58.0 min |
Chromium (Cr): 20.0 to 23.0% | Aluminium (Al): 0.40 max | Titanium (Ti): 0.40 max | Cobalt (Co): 1.0 max
Note: Mo = Molybdenum (8.0 to 10.0%), Nb = Niobium / Columbium (3.15 to 4.15%). These elements are the primary strengthening agents in Inconel 625 and are essential for its corrosion resistance and high-temperature performance.

Applications of Inconel 625 Sheets and Plates Across Industries
- Marine and Offshore: Inconel 625 plates are used in seawater handling systems, submarine hulls, offshore oil drilling platforms and marine exhaust systems due to their exceptional resistance to chloride-induced pitting and crevice corrosion. The high nickel content of the alloy makes it ideal for permanent immersion in seawater and brackish environments.
- Aerospace and Defence: ASTM B443 Alloy 625 sheet is specified for aircraft exhaust systems, thrust reverser assemblies, engine nacelles and fuel nozzles where temperatures exceed 800 degrees C. The alloy combines high oxidation resistance with excellent fatigue strength, meeting aerospace qualification standards.
- Chemical and Petrochemical: Alloy 625 plate is used in pressure vessels, heat exchanger headers, reactor linings and column internals handling phosphoric acid, hydrofluoric acid, seawater and mixed acid environments. Inconel 625 clad plates are used as a corrosion-resistant overlay on carbon steel pressure vessels and piping in chemical plants.
- Oil and Gas: UNS N06625 sheets and plates are specified for wellhead components, subsea equipment, flexible riser pipes and sour gas service environments where high strength, corrosion resistance and sour service compliance (NACE MR0175) are required.
- Power Generation: Inconel 625 coils and sheets are used in nuclear reactor core components, steam generator tubing and boiler systems where radiation resistance, creep strength and long service life are critical.
