Hastelloy C22 Threaded Rod: Why C22 for threaded rods
Threaded rod is cut to make studs and hangers. Available in full lengths or cut pieces. In Hastelloy C22, 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. Hastelloy C22 is picked for mixed oxidising and reducing acids, and weld overlays. |
|---|---|
| Typical service | Chemical processing — Equipment seeing both oxidising and reducing conditions. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Hastelloy C22 (bar to ASTM B574, where applicable), as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
