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 Flange (UNS N07750)
When you choose to buy Inconel X-750 flange, there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel X-750 Flange (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 Flange (UNS N07750)
When purchasing alloy flanges, it’s essential to have the right materials and information to ensure a smooth procurement process and to get the products that meet your project needs.
Here’s what you need to provide:
1. Material: Specify the flange material, such as nickel alloy X-750. You can refer to standards such as ASTM and ASME.
2. Type: Determine the type of flange needed, such as butt welding flange, threaded flange, slip-on flange, blind flange, etc.
3. Size: Specify the flange’s nominal diameter (DN) and pressure rating (PN).
4. Quantity: Provide the exact number of flanges required for an accurate quotation.
5. Technical specifications: Include technical specifications and drawings. If there are unique design requirements, detailed drawings can be attached.
6. Quality standards: Specify quality standards and inspection requirements, such as the need for third-party inspection, material certification, and inspection reports.
7. Special requirements: Specify any special surface treatment, coating, corrosion resistance requirements, etc.
8. Packaging requirements: If there are specific packaging needs, such as protective or anti-corrosion packaging, please specify.
9. Delivery time: Specify the expected delivery time and location.
By preparing the above information, you can streamline the process of purchasing flanges and ensure that you receive high-quality products that meet your requirements.
