Inconel X-750 Plate (UNS N07750) Drawing & Formula
Formula: m = W (m) × THK (mm) × L (m) × ρ (g/cm³)
W = Width, THK = Thickness, L = Length, ρ = Density
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 Plate (UNS N07750)
When you choose to buy Inconel X-750 Plate (UNS N07750) , there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel X-750
Inconel X-750 PREN: 44.8
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 Alloy X-750 Plate
