Inconel 600 Rectangular Tube: Why 600 for rectangular tubes
Rectangular tube is used for frames, supports and architectural work. 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 tubulars handle acids, chlorides and heat. 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) |
