Monel 400 Foundation Bolt: Why 400 for foundation bolts
Foundation bolts secure heavy machinery and structures. Supplied to drawing with nuts and washers. In Monel 400, 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. Monel 400 is picked for seawater, hydrofluoric acid and marine service. |
|---|---|
| Typical service | Marine — Pump shafts, valves and seawater piping. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Monel 400 (bar to ASTM B164, where applicable), as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
