Inconel® 625 Nickel-Chromium-Molybdenum Small Diameter Tubing

Inconel® 625 Nickel-Chromium-Molybdenum Small Diameter Tubing

Superior Strength & Corrosion Resistance from International Tube

At International Tube, we manufacture precision Inconel® 625 small diameter tubing (UNS N06625), a nickel-chromium-molybdenum-niobium alloy engineered for outstanding strength, fatigue resistance, and corrosion protection—even in the harshest operating environments. Inconel 625 is especially well-suited for high-pressure, high-temperature, and highly corrosive conditions, making it a preferred material in aerospace, marine, nuclear, and chemical processing industries.

With a carefully balanced composition—approximately 58% nickel, 20-23% chromium, 8-10% molybdenum, and 3-4% niobium—Inconel 625 delivers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments with seawater, acids, and oxidizing chemicals. It retains its mechanical integrity across a wide temperature range, from cryogenic to 1800°F (982°C).

Inconel 625 Tubing Features & Applications

Inconel 625 tubing from International Tube is trusted in critical systems that demand uncompromised material performance under severe stress and chemical exposure. Common applications include:

  • Marine and subsea components exposed to seawater and high pressure

  • Chemical processing systems handling aggressive acids and alkalis

  • Aerospace engine and exhaust assemblies

  • Nuclear reactor piping and steam systems

  • Pollution control systems and scrubber internals

  • Oil and gas production and transport systems

  • High-temperature instrumentation and sensor protection

At International Tube, our small-diameter Inconel 625 tubing is produced from premium alloy strip stock, plug drawn in coil form, and annealed as required to meet specific mechanical and temper requirements. We offer tubing in both straight lengths and continuous coil form, ideal for custom fabrication, automated processes, and high-performance assemblies.

When your application calls for maximum corrosion resistance, durability, and thermal stability, International Tube delivers Inconel 625 tubing engineered to exceed expectations in the most extreme environments.
