ASTM B444 UNS N06625 Inconel 625 Tubing
Inconel 625 tube (UNS N06625 / WNR 2.4856) is a high-performance nickel-chromium tubing solution prized for its mechanical strength and superior fabrication characteristics.
Overview of Inconel 625 Tubing Material
Inconel® 625 tubing is manufactured according to ASTM B163 and B516 standards, which specify various tube diameters and wall thicknesses while maintaining the consistency of the Inconel 625 material. The alloy is carefully stabilized with elements such as titanium, tantalum, columbium, and molybdenum, which enhance its properties. Also, an annealing heat treatment process of a solid solution makes its mechanical strength even better. Inconel 625 tube has distinguished tensile strength of at least 940 MPa and a minimum 430 Mpa yield strength.

Inconel 625 tubes are used in aerospace, marine, chemical processing, and nuclear industries. Their excellent resistance to heat, corrosion, and high-pressure environments makes them ideal for heat exchangers, exhaust ducts, reactor piping, and offshore components.
Inconel 625 tubing performs reliably across a wide temperature range, from cryogenic levels up to around 982°C (1800°F). Its ability to retain strength and resist oxidation at extreme temperatures makes it ideal for thermal and high-stress applications.
Yes, Inconel 625 tubes offer outstanding resistance to seawater corrosion, including pitting and crevice corrosion. Their high nickel and molybdenum content makes them suitable for marine applications like seawater piping, risers, and offshore structures.
Inconel 625 tubes are manufactured to ASTM B163, B444, B516, and ASME SB standards. These cover seamless and welded tubing used in heat exchangers, boilers, and condensers requiring high strength, corrosion resistance, and thermal stability.
Seamless Inconel 625 tubing offers superior strength and uniformity, ideal for high-pressure uses. Welded tubing is more economical and suited for lower-stress applications but must be inspected for weld quality to ensure performance under critical conditions.
