Inconel 718 Plate (UNS N07718) Applications & Usages
Inconel 718 is widely utilized across the aviation and aerospace industries, where components must perform reliably under extreme temperature and pressure conditions. Engineers choose this superalloy for its exceptional combination of strength, corrosion resistance, and cost-effectiveness, as well as its ability to maintain mechanical integrity in both high and low temperature environments.
In the hottest sections of jet engines, where mechanical and atmospheric stresses are severe, Inconel 718 provides outstanding resistance to oxidation and creep. Typical aerospace applications include jet engine and high-speed airframe components such as discs, fasteners, spacers, rings, bolts, and instrumentation parts.
Beyond aerospace, Inconel 718 is also employed in liquid-fueled rocket components, turbine engine sheet metal parts, and casings for both aircraft and land-based turbines.
At the opposite end of the temperature spectrum, its toughness and stability make it equally suitable for cryogenic storage and tankage applications.
Inconel 718 Plate (UNS N07718) Drawing & Formula
Formula: m = W (m) × THK (mm) × L (m) × ρ (g/cm³)
W = Width, THK = Thickness, L = Length, ρ = Density

More Information About Inconel Alloy 718 Plate
When you choose to buy Inconel 718 plate, there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel 718
Inconel 718 PREN: 31
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 718 Plate
