Inconel 625

Aurico Alloys LLP supplies Inconel 625 (UNS N06625, W.Nr. 2.4856) as sheet, plate, coil, foil, round bar, wire, pipe, tube and fittings, from Mumbai, India, with EN 10204 3.1 mill test certificates. It offers outstanding seawater, sour gas and high-temperature corrosion resistance for marine, oil & gas, power, chemical and pharma plants.

Key Properties

Molybdenum 8-10% with chromium 20-23% on nickel 58% minimum — corrosion resistance in both oxidising and reducing conditions.
Strength without heat treatment. It reaches high strength in the annealed condition, so welded fabrications need no post-weld ageing.
Iron to 5% and carbon to 0.10%, with aluminium and titanium each capped at 0.40%.
Seawater and chloride service as well as high temperature, which is why it is the most widely specified grade in the family.

Applications

Seawater and subsea hardware
Chemical process piping and vessels
Aerospace ducting and exhaust systems
Flue gas desulphurisation and scrubbers

Special Metals rates Inconel 625 excellent in phosphoric and organic acids and good in nitric acid, at about 0.76 mm/a in boiling 65%. Where it ranks against the other grades in each acid is set out in our acid and alkali service guide.
