Incoloy 825 Strip (UNS N08825 / W.Nr. 2.4858)
High-strength corrosion-resistant alloy strips for chemical processing and pollution control system
As an experienced nickel alloy strip supplier, SEATHER TECHNOLOGY manufactures high-quality Incoloy 825 (UNS N08825) strips in a wide range of sizes to meet diverse industrial needs.
Incoloy 825 is a versatile nickel-iron-chromium alloy known for its excellent corrosion resistance, particularly in acidic, marine, and chemical processing environments. With strong resistance to stress-corrosion cracking, pitting, and intergranular attack—combined with a relatively cost-effective price—Incoloy 825 is extensively used in marine engineering, chemical plants, oil & gas equipment, and heat exchangers.
SEATHER produces Incoloy 825 strip strictly according to ASTM B424.
- For strip widths above 200 mm, we slit high-quality Incoloy 825 coils to ensure dimensional accuracy and surface quality.
- For widths below 200 mm, we manufacture strip by precision cold rolling, allowing tighter control of mechanical properties and improved uniformity.
At narrow widths, mechanical requirements—such as tensile strength or hardness—may vary depending on your application. Please confirm any specific requirements with us. Our technical team will evaluate your needs and provide material customized to your performance criteria.

More Information About Incoloy 825 Strip (UNS N08825)
When you choose to buy Incoloy 825 Strip (UNS N08825), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Incoloy 825
Incoloy 825 PREN: 31.4
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 Incoloy 825 Strip
