Inconel 718 Cold-rolled Plate: Why 718 for cold-rolled plates
Cold-rolled plate has tighter thickness tolerance and a smoother surface than hot-rolled. 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 plate goes into vessels and tube sheets in aggressive media. 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. |
| Matching filler | ERNiFeCr-2 (AWS A5.14) |
