| Inconel 718 | Nickel-based, age-hardenable | 704 °C | Excellent | 1240 MPa | Aerospace, Power generation, Oil & gas |
| Monel 400 | Nickel-Copper | 538 °C | Excellent (marine, hydrofluoric) | 550 MPa | Marine, Chemical, Heat exchangers |
| Super Duplex 2507 | Super duplex stainless | 300 °C | Outstanding (pitting-resistant) | 800 MPa | Subsea, Offshore, Chemical |
Choosing between alloys
When should you choose Inconel 625 over Hastelloy C-276?
Inconel 625 outperforms in high-temperature oxidizing service (>700 °C). Hastelloy C-276 is preferred for aggressive reducing acids and chloride environments at moderate temperatures.
When does Super Duplex 2507 replace Inconel?
Super Duplex matches many Inconel grades for chloride pitting resistance at a lower cost in the temperature range up to ~300 °C — but loses mechanical performance above that range, where Inconel becomes essential.
Why specify EN 10204 3.2 over 3.1?
3.2 certification adds an independent inspector's verification, required for nuclear, pressure-vessel, and certain offshore applications under PED 2014/68/EU.
