Inconel X-750 Seamless Pipe Tube (UNS N07750 / W.Nr. 2.4669)
High-strength corrosion-resistant alloy Pipe Tube for nuclear power and heat treatment
As a professional superalloy supplier, SEATHER TECHNOLOGY manufactures and supplies high-performance Inconel X-750 seamless pipe and tube for critical applications operating under extreme high-temperature and high-pressure conditions.
INCONEL® alloy X-750 (UNS N07750 / W.Nr. 2.4669) is a precipitation-hardenable nickel-chromium-based superalloy renowned for its exceptional high-temperature strength, oxidation resistance, and long-term creep resistance. Through solid solution strengthening and aging treatment, Inconel X-750 maintains excellent mechanical stability at temperatures above 700 °C, making it an ideal material for aerospace, energy, chemical processing, and nuclear industries.
Compared with ordinary stainless steels, Inconel X-750 seamless pipe & tube offers significantly superior tensile strength, fatigue life, and resistance to thermal deformation, effectively reducing the risk of cracking or failure during long-term high-temperature service. Its high chromium content forms a dense and stable oxide layer, providing outstanding resistance to oxidation, sulfidation, and chloride-containing corrosive media.
Our Inconel X-750 seamless pipes and tubes are produced using high-quality raw materials and advanced cold drawing or cold rolling processes, ensuring a uniform microstructure and precise dimensional control. To meet stringent safety and reliability requirements, every pipe undergoes 100% hydrostatic testing to verify pressure integrity and leak-free performance. In addition, eddy current testing is performed to detect surface and near-surface defects with high sensitivity, eliminating potential risks such as micro-cracks or inclusions.
SEATHER TECHNOLOGY implements strict quality control systems throughout production. We can provide complete inspection documentation, including chemical composition analysis, mechanical property testing, non-destructive testing reports, and material test certificates, ensuring full compliance with applicable international standards and customer specifications.

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 Seamless Pipe Tube (UNS N07750)
When you choose to buy Inconel X-750 Seamless 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 Seamless Pipe Tube (UNS N07750)
