High-strength corrosion-resistant alloy Coil for marine and chemical processing
As a trusted and competitive supplier of Inconel materials, SEATHER TECHNOLOGY manufactures high-quality Inconel 625 coils with reliable performance and cost-effective pricing.
Inconel 625 (UNS N06625 / W.Nr. 2.4856) is a nickel-chromium-molybdenum alloy renowned for its exceptional strength, outstanding corrosion resistance, and excellent fabricability, including superior weldability. It is suitable for a wide range of service temperatures—from cryogenic conditions up to 1800°F (982°C)—making it one of the most versatile superalloys for demanding industrial applications.
Inconel 625 coil is produced by rolling Inconel 625 sheet or plate into a continuous coil form. Based on the production method, SEATHER offers two main types:
- Hot Rolled Inconel 625 Coil – supplied with a No.1 finish
- Cold Rolled Inconel 625 Coil – supplied with a standard 2B finish
After uncoiling and flattening, the material can be further processed into Inconel 625 sheets or plates. Customized surface finishes are also available according to your project requirements—please contact us to confirm specifications.

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