Inconel 825 Threaded Rod: Why 825 for threaded rods
Threaded rod is cut to make studs and hangers. Available in full lengths or cut pieces. 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 and sour gas. |
|---|---|
| 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 such as Inconel 825 from ASTM B425, as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
