Duplex 2205 Anchor Bolt: Why 2205 for anchor bolts
Anchor bolts are cast into or drilled into concrete foundations for columns and equipment. In Duplex 2205, 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 | Duplex fasteners add strength in chloride service. Duplex 2205 is picked for strength with chloride resistance at a stainless-steel budget. |
|---|---|
| Typical service | Oil & gas — Flowlines, manifolds and topside piping. |
| Bolting | B7 (coated), B8M or duplex studs, as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
