Inconel 625 Plate & Sheet Suppliers in India
Inconel 625 Plate, Inconel 625 Sheet, Alloy 625 Strip, Nickel Alloy 625 Coil, UNS N06625 Foil, 2.4856 Shim Sheet, AMS 5599 Sheet and AMS 5869 Foil.
Jade Alloys is an Inconel 625 sheets and plates supplier, stockist and exporter in India, with ready stock in Mumbai from 0.3 mm to 120 mm. Inconel 625 (UNS N06625, Werkstoff 2.4856, Alloy 625) is a nickel-chromium-molybdenum alloy strengthened by niobium. The niobium works with the molybdenum as a solid-solution strengthener, so the plate reaches very high strength and toughness with no heat treatment. An Inconel 625 plate resists oxidation to about 1800 degrees Fahrenheit, is non-magnetic, and is immune to chloride-ion stress corrosion cracking, which is why it holds up in sea water, acids and sour gas where stainless steel fails.
We supply Inconel 625 sheet, plate, strip, slit coil, foil, shim sheet and clad plate to ASTM B443, ASME SB443, AMS 5599 and AMS 5869, with a minimum order of a single sheet. The range sits alongside our Inconel 625 round bar, pipes and tubes and fasteners, and forms part of our wider Inconel sheets and plates range. Every order carries an EN 10204 3.1 mill test certificate, with 100% radiography, PMI, NACE MR0175 and third-party inspection on request.

Fabrication of Inconel 625 Sheets & Plates
- Welding
Inconel 625 is readily welded by TIG, MIG, SAW and plasma processes, using ERNiCrMo-3 filler. Post-weld heat treatment is generally not required.
- Cold Forming
Cold form using standard austenitic stainless methods. Process anneal at 927 to 1038 degrees C to restore ductility between heavy forming steps. - Hot Forming
Hot form up to a maximum furnace temperature of 1149 degrees C, and reheat below 1010 degrees C for finishing. - Machining
Machine in the annealed condition at low speeds and positive feeds to avoid work hardening. - Heat Treatment
| Treatment | Temperature | Cooling |
|---|---|---|
| Solution Annealing | 1093 to 1204 degrees C | Air or water |
| Stress Relieving | 870 to 1040 degrees C | Air |
| Annealing (softening) | 927 to 1038 degrees C | Rapid air |
Corrosion Resistance of Inconel 625 Plates & Sheets
- Excellent resistance to pitting and crevice corrosion

- Outstanding oxidation resistance to about 980 degrees C
- NACE MR0175 compliant for sour service
- Resists sea-water impingement and marine corrosion
Typical general corrosion rate of Inconel 625 plate is around 0.2 mm/year (7.9 mpy) in aggressive media.
Applications of Inconel 625 Sheets & Plates
Inconel 625 sheets and plates are used across oil and gas, marine and offshore, chemical and petrochemical, aerospace and defence, power generation and pollution control. Typical parts include aircraft ducting, jet engine exhaust and thrust-reverser systems, specialised sea-water equipment, heat exchangers, pressure vessels, flare stacks and chemical process equipment, wherever high strength must survive heat and aggressive corrosion.
