Applications of ASTM B424 UNS N08825 Incoloy 825 Plate
1. Chemical processing industry
Reactors, storage tanks, heat exchangers, piping systems.
2. Oil and gas
- Sour oil and gas fields (H₂S/CO₂ environment): used for downhole tools, valves, pipelines.
- Offshore platform: seawater treatment system (such as pump casing, desalination equipment)
3. Pollution control and environmental protection
Flue gas desulfurization (FGD) system: absorption tower lining, flue, scrubber components, resistant to sulfur-containing wet flue gas and chloride corrosion.
4. Marine engineering
- Evaporators, pipelines, resistance to chloride ion corrosion and biological contamination.
- Ship parts: propeller shaft, seawater pump, suitable for high salt spray environment
5. High temperature application
Heat treatment furnace parts: ASTM B424 UNS N08825 Plate resistant to high temperature oxidation (up to 550°C), used for furnace rollers and combustion chamber liners.
6. Pulp and paper industry
Bleaching equipment and digesters: resist corrosion from highly corrosive chemicals such as chlorides and chlorine dioxide.

Why choose ASTM B424 UNS N08825 Plate?
Corrosion Resistance
- Acidic environment: resistant to sulfuric acid (concentration ≤70%), phosphoric acid, acetic acid and mixed acids.
- Alkaline environment: resistant to caustic alkali (such as NaOH) corrosion.
- Chlorine-containing environment: resistant to pitting and stress corrosion cracking (SCC) caused by seawater, salt spray, and chloride solution.
- Resistant to hydrogen sulfide (H₂S) corrosion: in the acidic environment of oil and gas production (containing H₂S/CO₂)
High Strength
- Room temperature tensile strength ≥586 MPa, yield strength ≥241 MPa. Good ductility (elongation ≥ 30%), avoiding brittle fracture.
