An Inconel 825 anchor bolt is a bolt that fixes structures or equipment to concrete. Finished fastener specification not asserted; material/feedstock may be supplied to ASTM B425 (UNS N08825), where applicable; manufacturing route and finished fastener requirements are to the purchase specification or project drawing. Anchor bolts are cast into or drilled into concrete foundations for columns and equipment.
See the Inconel 825 fasteners grade form page for standards and sizes.

Inconel 825 Anchor Bolt: Why 825 for anchor bolts
Anchor bolts are cast into or drilled into concrete foundations for columns and equipment. In Inconel 825, 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 825 is picked for sulphuric and phosphoric acid service, chloride stress-corrosion cracking. |
|---|---|
| Typical service | Sulphuric & phosphoric acid plants — Tank linings, agitators, heat-exchanger baffles in fertiliser and acid production. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Inconel 825 (bar to ASTM B425, where applicable), as the project specifies |
