H2: What is Inconel 825? (Nickel-Iron-Chromium Alloy with Molybdenum & Copper)
Inconel 825 (UNS N08825, W.Nr. 2.4858) is a high-performance corrosion-resistant alloy designed for aggressive chemical and marine environments.
It is considered the ideal alloy for acid-handling equipment and marine applications.
sulfuric acid vessels, heat exchangers, evaporators
seawater systems, risers, pumps, propeller blades
flue gas scrubbers, ducts, stack liners
sour gas service piping, separators, flare stacks
fuel reprocessing and waste handling equipment
chemical cleaning & highly corrosive environments
| Property | Typical Value | Notes |
|---|---|---|
| Tensile Strength | ~550 MPa | Strong under corrosive load conditions |
| Yield Strength | ~220 MPa | Maintains strength in pressure vessels |
| Elongation | 30–40% | Good ductility & formability |
| Hardness (Rockwell B) | ~80–90 HRB | Balanced machinability + strength |
Offers strength + corrosion resistance in both acidic and marine environments.
| Element | Typical % | Function |
|---|---|---|
| Nickel (Ni) | 38–46 | Corrosion resistance & chloride SCC resistance |
| Iron (Fe) | 22 min | Base element for strength & stability |
| Chromium (Cr) | 19.5–23.5 | Oxidation resistance |
| Molybdenum (Mo) | 2.5–3.5 | Pitting & crevice corrosion resistance |
| Copper (Cu) | 1.5–3.0 | Resistance to sulfuric & phosphoric acid |
| Titanium (Ti) | 0.6–1.2 | Prevents intergranular corrosion |
| Carbon (C) | 0.05 max | Maintains weldability |
This chemistry makes Inconel 825 one of the best alloys for acid-handling equipment.
