Inconel 625

Each element contributes specific performance benefits. Nickel (58–70%) provides a stable austenitic matrix, ensuring excellent ductility, good fabricability, and outstanding resistance to chloride‑induced stress corrosion cracking. Chromium (20–23%) delivers strong resistance against oxidizing media such as nitric acid and high‑temperature oxidation. Molybdenum (8–10%) together with niobium (3.15–4.15%) imparts superior resistance to pitting, crevice corrosion, and reducing acids, while also providing high strength without the need for precipitation hardening. The addition of niobium stabilizes the alloy against sensitization and enables age‑hardening responses in some tempers. This balanced composition gives Inconel 625 exceptional corrosion resistance and high mechanical strength from cryogenic temperatures up to about 980°C.

viaken supplies Inconel 625 in three key forms: tubes/pipes, coiled strip, and plates/sheets.

Typical application fields and the corresponding uses of each form are listed below:

1.Chemical & petrochemical industry

Tubes/pipes – Process piping and heat exchanger tubing for corrosive fluids (e.g., acids, sour gas).

Coiled strip – Linings for reaction columns, expansion joints, and flexible hoses.

Plates – Reactor vessels, distillation towers, and storage tanks handling aggressive chemicals.
