Inconel 600 U-bolt: Why 600 for u-bolts
U-bolts hold pipes to supports and structures. Sized by pipe NPS with a threaded length on each leg. In Inconel 600, 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 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| Bolting | B7 (coated), B8M or nickel-alloy studs such as Inconel 600 from ASTM B166, as the project specifies |

FOB / CIF · Nhava Sheva (JNPT), MumbaiInconel 600 U-bolt — questions buyers ask
Should U-bolts match the pipe material?
Use the same alloy, or an isolating sleeve, to avoid galvanic corrosion between pipe and bolt.
What nut is used with Inconel 600 u-bolts?
A nut in the same alloy, machined from ASTM B166 bar, unless the project specifies otherwise.
Which standard covers Inconel 600 u-bolts?
The material is ASTM B166; dimensions follow MSS SP-58 / manufacturer standard. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Inconel 600 u-bolt?
The alloy price, the size and dimensions, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
