Incoloy 825 Mesh
Key Features:
- Excellent corrosion resistance to sulfuric acid, phosphoric acid, and seawater
- Resists pitting & crevice corrosion in chloride-rich environments
- High nickel & molybdenum content for enhanced durability
- Copper improves resistance to sulfuric and phosphoric acids
- Good mechanical strength from cryogenic to moderately high temperatures (1000°F)
Product Description:
Incoloy 825 mesh is a nickel-iron-chromium alloy mesh with additions of molybdenum and copper, designed for exceptional resistance to corrosive acids, seawater, and reducing environments. It is widely used in chemical processing, oil & gas, and marine applications where standard stainless steels (e.g., 316L) fail.
Key Features of Incoloy 825 Mesh:
✔ Excellent corrosion resistance to sulfuric acid, phosphoric acid, and seawater
✔ Resists pitting & crevice corrosion in chloride-rich environments
✔ High nickel (38-46%) & molybdenum (2.5-3.5%) content for enhanced durability
✔ Copper (1.5-3%) improves resistance to sulfuric and phosphoric acids
✔ Good mechanical strength from cryogenic to moderately high temperatures (~540°C / 1000°F)
Common Applications:
– Chemical Processing
– Acid filtration, reactor screens, scrubber components
– Oil & Gas (Sour Service)
– Downhole screens, offshore platforms, piping systems
– Marine & Desalination
– Seawater filtration, heat exchangers, condenser screens
– Pollution Control
– Flue gas desulfurization (FGD), waste treatment
– Nuclear Fuel Reprocessing
– Handling nitric acid and radioactive solutions
