Inconel 625 Anchor Bolt: Why 625 for anchor bolts
Anchor bolts are cast into or drilled into concrete foundations for columns and equipment. In Inconel 625, 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 625 is picked for seawater, high strength and high temperature in one alloy. |
|---|---|
| Typical service | Offshore & subsea — Risers, flowlines and clad pipe. |
| Bolting | B7 (coated), B8M or nickel-alloy studs such as Inconel 625 from ASTM B446, as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
