Superalloy Inconel 718
We handle Inconel 718 scrap and turnings in regular volumes for European foundries and refiners, with fast quotations and dedicated collection.
Nickel-iron precipitation-hardening superalloy (γ''), with high mechanical strength up to ~700 °C. It is the most widely used alloy for turbine discs and blades. Markets: aerospace, gas turbines, oil & gas.
- Forms scrap · turnings · cut-offs · casting residues
- Density 8.19 g/cm³
- Rm up to ~1350 MPa
Main elements
| Chromium (Cr) | 17.0 – 21.0 % |
|---|---|
| Iron (Fe) | ≈ 17 – 21 % (balance) |
| Niobium + Tantalum (Nb+Ta) | 4.75 – 5.50 % |
| Molybdenum (Mo) | 2.8 – 3.3 % |
| Titanium (Ti) | 0.65 – 1.15 % |
| Aluminium (Al) | 0.20 – 0.80 % |
| Nickel + Cobalt (Ni+Co) | 50.0 – 55.0 % |
Indicative values according to ASTM B637 / AMS 5662 and UNS N07718. The actual composition is certified for each batch.
Physical and mechanical data
