Inconel X-750 Welded Pipe Tube (UNS N07750 / W.Nr. 2.4669)
High-strength corrosion-resistant alloy Pipe Tube for nuclear power and heat treatment
As a leading Chinese Inconel pipe supplier, SEATHER TECHNOLOGY manufactures and supplies Inconel X-750 welded pipe and tube in a wide range of sizes to meet the demanding requirements of high-temperature and high-strength applications.
INCONEL® alloy X-750 (UNS N07750 / W.Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy widely recognized for its excellent corrosion resistance, oxidation resistance, and high-temperature strength. The alloy retains outstanding mechanical properties at temperatures up to 1300°F (704°C) and, after appropriate heat treatment, maintains useful strength even at temperatures approaching 1800°F (982°C). These characteristics make Inconel X-750 an ideal material for aerospace, energy, chemical processing, and nuclear engineering applications.
Inconel X-750 welded pipe & tube is manufactured by forming and welding high-quality Inconel X-750 strip or plate, making raw material selection and welding technology critical to final product performance. At SEATHER TECHNOLOGY, we source premium raw materials from reputable large-scale mills and apply advanced strip splitting, precision forming, and automated welding processes to ensure consistent weld quality, dimensional accuracy, and structural integrity.
To meet higher service requirements, we can supply solution-annealed Inconel X-750 welded pipes and tubes, using our online solid solution heat treatment equipment. This process effectively relieves residual stress, improves microstructural uniformity, and enhances high-temperature performance and corrosion resistance. Additional non-destructive testing and inspection services can also be provided upon request to ensure full compliance with international standards and customer specifications.

Inconel X-750 Welded Pipe Tube (UNS N07750) Drawing & Formula
Formula: m = (OD – THK) × THK (mm) × L (m) × ρ (g/cm³) × π ÷ 1000
OD = Outside Diameter, THK = Wall Thickness, L = Length
ρ = Density, π = 3.1415926…
What is Inconel X-750 (UNS N07750)
Alloy X-750 also referred to as the UNS N07750 and W.Nr. 2.4669 alloy.
Alloy X-750 is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F.
Alloy X-750 also has excellent properties down to cryogenic termperatures.
Similar to Alloy 600, Alloy X-750 has additional aluminium and titanium.
Alloy X-750 offers outstanding performance in highly stressed environments, which is why it’s often used in gas turbines, nuclear reactors and aircraft structures.

More Information About Inconel X-750 Welded Pipe Tube (UNS N07750)
When you choose to buy Inconel X-750 Welded Pipe Tube, there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel X-750 Seamless Pipe Tube (UNS N07750)
Inconel X-750 PREN: 16
The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:
PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%How to Purchase Inconel X-750 Welded Pipe Tube (UNS N07750)
