Super Duplex 2507 Eye Bolt: Why 2507 for eye bolts
Eye bolts provide lifting points on equipment. Load ratings depend on angle of pull. In Super Duplex 2507, 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. Super Duplex 2507 is picked for seawater and high-chloride service where strength also matters. |
|---|---|
| Typical service | Offshore & subsea — Seawater injection, firewater and subsea 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 |
