Inconel 718 vs Inconel 625 Flanges – Comparison
| Property | Inconel 718 (UNS N07718) | Inconel 625 (UNS N06625) |
|---|---|---|
| Main Feature | Very high strength | Excellent corrosion resistance |
| Strength | Extremely high (age-hardenable) | High but lower than 718 |
| Yield Strength | ~1030 MPa (aged condition) | ~460 MPa |
| Tensile Strength | ~1240 MPa | ~827 MPa |
| Temperature Resistance | Up to 700°C approx | Up to 980°C approx |
| Corrosion Resistance | Very good | Outstanding (especially marine & chemical) |
| Weldability | Good | Excellent |
| Fabrication | More difficult (heat treated alloy) | Easier to fabricate |
| Cost | Generally higher | Slightly lower than 718 |
| Common Applications | Aerospace, turbines, high-pressure bolts | Marine, chemical plants, oil & gas |
Which One Should You Choose?
-
Choose Inconel 718 flanges when high strength and mechanical performance are critical.
-
Choose Inconel 625 flanges when corrosion resistance in harsh chemical or marine environments is the priority.
