Inconel 718 Anchor Bolt: Why 718 for anchor bolts
Anchor bolts are cast into or drilled into concrete foundations for columns and equipment. 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 fasteners match nickel-alloy flanges in corrosive or hot service. 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. |
| Bolting | B7 (coated), B8M or nickel-alloy studs such as Inconel 718 from ASTM B637, as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
