An Inconel 600 nipple is a short length of pipe, threaded or plain, used to connect fittings, made from Inconel 600 to ASTM B564. Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends.

Inconel 600 Nipple: Why 600 for nipples
Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends. 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 fittings match nickel-alloy pipe in aggressive media. Inconel 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| Welding to carbon steel | A nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel |
| Matching filler | ERNiCr-3 (AWS A5.14) |

Inconel 600 Nipple — questions buyers ask
What is a swage nipple?
A nipple that reduces from one size to another, concentric or eccentric, to MSS SP-95.
Can Inconel 600 nipples be welded to carbon steel?
Yes — a nickel-base filler such as ERNiCr-3 (or ERNiCrMo-3) is used when joining it to carbon steel.
Which standard covers Inconel 600 nipples?
The material is ASTM B564; dimensions follow MSS SP-95 · ASME B36.10 / B36.19. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Inconel 600 nipple?
The alloy price, the size and schedule or class, 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 or 3.2 certificates available on request / as specified in the PO; dimensional reports as required. PMI can be arranged depending on product and requirements, as specified in the PO.
