Inconel 625 Plate (UNS N06625) Applications & Usages
Nickel alloy 625 is widely used in marine applications due to its outstanding corrosion resistance. Its ability to withstand localized corrosion (pitting and crevice corrosion), chloride ion stress corrosion, and its excellent fatigue strength make it ideal for marine components such as propeller blades, exhaust systems, and fasteners.
Additionally, alloy 625 is extensively employed in the aerospace industry for its superior high-temperature tensile properties and creep strength. It is commonly used in aircraft piping systems, engine exhausts, fuel and hydraulic lines, and heat exchanger tubes. Its high-temperature resistance also makes it valuable in heat treatment equipment and the chemical industry.
Inconel 625 Plate (UNS N06625) 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 625 Plate
When you choose to buy Inconel 625 plate, there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel 625
Inconel 625 PREN: 40.8
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 625 Plate
