Inconel 625 Sheet (UNS N06625 / W.Nr. 2.4856)
High-strength corrosion-resistant alloy sheet for marine and chemical processing
As a leading Inconel materials supplier in China, SEATHER TECHNOLOGY manufactures and delivers cost-effective, high-quality Inconel 625 sheets tailored to the needs of global industrial applications.
Inconel 625 (UNS N06625 / W.Nr. 2.4856) is a nickel-chromium-molybdenum alloy known for its exceptional strength, superior fabricability (including excellent weldability), and outstanding resistance to a wide range of corrosive environments. With a service temperature range from cryogenic levels up to 1800°F (982°C), it is commonly used in chemical processing, marine engineering, aerospace, and high-temperature equipment.
Inconel 625 sheet is typically produced by flattening and shearing cold-rolled Inconel 625 coil. Cold-rolled sheets generally come in thicknesses below 5 mm and feature a brighter, finer surface finish compared to hot-rolled plate. These sheets offer excellent mechanical performance—high tensile strength, superior creep resistance at elevated temperatures, and significantly better fatigue resistance than conventional alloy sheets. In addition, Inconel 625 sheet provides exceptional oxidation resistance, enabling long-term service in aggressive or high-temperature environments.

What is Inconel 625 (UNS N06625)
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.

More Information About Inconel 625 Sheet (UNS N06625)
When you choose to buy Inconel 625 Sheet (UNS N06625), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Inconel 625 Sheet
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 625 Sheet (UNS N06625)
