Inconel 718 Slit Coil: Why 718 for slit coils
Slit coils feed stamping, roll forming and tube mills. State width, tolerance and coil weight. In Inconel 718, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Nickel-alloy strip is slit for bellows, springs and precision parts. Inconel 718 is picked for very high strength at temperatures up to about 650 °C. |
|---|---|
| Typical service | Oil & gas — Wellhead parts, hangers and high-strength bolting. |
