How to Verify Inconel 600 Coil with PMI
Positive material identification with a handheld XRF gun confirms the alloy on the piece itself, in seconds, before it is cut or welded. Inconel 600 is most often mixed up with Incoloy 800 / 800H / 800HT — the table shows which elements tell them apart.
Handheld XRF does not measure carbon or nitrogen; those come from the mill certificate or optical emission (OES) testing. PMI can be arranged on request — state it on your enquiry.

Inconel 600 Coil Applications
Inconel 600 is specified when the cheaper grade will not survive the service but a higher alloy would be more than the job needs. These are the jobs our buyers use it for.
Inconel 600 Coil vs 310S, 800 and 625
| Grade | Coil standard | PREN (approx.) | Pick it when |
|---|---|---|---|
| Incoloy 800 / 800H / 800HT | ASTM B409 | — | Furnaces, petrochemical heaters and high-temperature piping |
| Inconel 600 | ASTM B168 | — | High-temperature oxidation, caustic and nuclear service |
| SS 310 / 310S | ASTM A240 | ≈ 25 | Furnaces, burners and heat treatment at high temperature |
| Inconel 625 | ASTM B443 | ≈ 51 | Seawater, high strength and high temperature in one alloy |
PREN = Cr + 3.3 Mo + 16 N, from mid-range chemistry. A screening guide, not a substitute for corrosion data on your medium.
Inconel 600 Corrosion Resistance — Element by Element
Each alloying addition has a job. Knowing which one protects against your medium is the quickest way to judge whether 600 fits.
Very high nickel content makes 600 practically immune to chloride stress-corrosion cracking and very good in caustic soda.
Chromium gives oxidation resistance to about 1175 °C.
Resists carburising and nitriding atmospheres in furnaces.
Not a first choice for sulphuric or hydrochloric acid — see 825 or C276.
How your 600 coil order runs
- 01Enquiry review — we confirm size, standard edition and documents against your MR or drawing.
- 02Heat selection & PMI — the mill certificate is checked against your order; PMI can be arranged depending on product and requirements, as specified in the PO.
- 03Processing — cutting, machining or bevelling to your specification, with heat numbers marked as specified in the PO.
- 04Inspection — your third-party inspector witnesses, or we share photos and test reports.
- 05Packing & dispatch — seaworthy packing from Nhava Sheva (JNPT), Mumbai, FOB or CIF, documents sent before the vessel sails.
Welding & Fabricating Inconel 600 Coil
Inconel 600 welds by all common arc processes. A few points our buyers ask about:
| Matching filler | ERNiCr-3 (AWS A5.14) |
|---|---|
| Over-alloyed filler | ENiCrFe-3 electrode |
| Preheat | Not required; keep interpass temperature low |
| Cutting | Thermal or abrasive cutting; grind off heat-tinted edges before welding |
Follow your approved WPS; this is general guidance. See also 600 fittings and 600 flanges for the matching pipe-system parts.

Inconel 600 coil — questions buyers ask
Is Inconel 600 the same as Alloy 600?
Alloy 600, UNS N06600, W.Nr 2.4816 are names used for Inconel 600 (W.Nr / EN numbers and older UNS variants are the closest designations; their limits can differ slightly, so specify the UNS number and ASTM grade on the order), and coil is ordered to ASTM B168 whichever name is on the enquiry.
Can Inconel 600 coil be slit to width?
Yes. Coils can be slit to narrow widths for stamping, tube making and spring work; state width tolerance and coil weight on the enquiry.
What inner diameter do Inconel 600 coils have?
508 mm (20") and 610 mm (24") are the common IDs. Tell us your decoiler ID and maximum coil weight and we slit to suit.
Can I order Inconel 600 cut-to-length sheets from coil?
Yes. Coil can be levelled and cut to length; state length tolerance and flatness.
Inconel 600 or Inconel 625 — which should I choose?
Inconel 600 is chosen for high-temperature oxidation, caustic and nuclear service. Inconel 625 is the step up when you need more pitting resistance or strength. See the comparison table on this page, or ask us with your process conditions.
