MANUFACTURING PROCESS
Reliable Production For Critical Applications
Flat C-276 product passes through melt, slab rolling, cold rolling, and a water-quenched anneal before it is cut to size. In addition, the sequence changes with the ordered gauge, standard, and acceptance level.
01
Melt and Chemistry Control
Nickel, chromium, molybdenum, and tungsten charge melts to the N10276 window with carbon at 0.010% max.
02
Refining
AOD or vacuum treatment lowers carbon, silicon, and gas content, and ESR refines heats bound for critical service.
03
Slab Rolling
The mill reduces slabs to plate gauge on a schedule set for the ordered thickness.
04
Sheet and Strip Rolling
Cold mills bring sheet and strip to final gauge, which tightens tolerance and surface finish.
05
Solution Annealing
The line heats material to 1120–1160 °C and quenches it in water to dissolve precipitates.
06
Cutting and Release
Leveling and cutting to size follow, then the batch clears inspection against the ordered acceptance level.

|---|---|
| Nickel (Ni) | 57.0% min. (balance) |
| Molybdenum (Mo) | 15.0–17.0% |
| Chromium (Cr) | 14.5–16.5% |
| Tungsten (W) | 3.0–4.5% |
| Iron (Fe) | 4.0–7.0% |
| Cobalt (Co) | 2.50% max. |
| Manganese (Mn) | 1.00% max. |
| Vanadium (V) | 0.35% max. |
| Silicon (Si) | 0.08% max. |
| Carbon (C) | 0.010% max. |
| Phosphorus (P) | 0.040% max. |
| Sulphur (S) | 0.030% max. |
Mechanical Properties
Minimum values below follow ASTM B575 for the solution-annealed condition, which is the condition the standard lists for this grade. Therefore, confirm the ordered gauge and condition before acceptance.
| Product Form | Standard | Condition | Tensile Strength | Yield Strength, 0.2% Offset | Elongation |
|---|---|---|---|---|---|
| Hot-rolled plate | ASTM B575 | Solution annealed | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
| Cold-rolled sheet and strip | ASTM B575 | Solution annealed | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
| Cut blanks and profiled plate | ASTM B575 | Solution annealed | ≥690 MPa (100 ksi) | ≥283 MPa (41 ksi) | ≥40% |
Hardness on annealed flat product normally falls at or below 100 HRB. Aerospace flat product runs to AMS 5530, which adds melting practice, surface, and examination controls. Confirm the ordered condition at enquiry so the right document is quoted.

ASTM International issues the flat-rolled documents. Besides, the ASME SB575 edition governs wherever a vessel falls under pressure-code jurisdiction.
Exposure between roughly 650 and 1090 °C during fabrication can precipitate intermetallic phases, so hot forming needs a follow-up solution anneal. Our engineers review that step with your shop before the plate leaves.

FAQ
Frequently Asked Questions
Which ASTM standard covers Hastelloy C-276 plate and sheet?
You order flat-rolled C-276 product to ASTM B575, which sits alongside B906 general requirements. Additionally, ASME SB575 applies under code jurisdiction.
What thickness range is available for C-276 plate?
Gauges run from 0.5 mm coil through 100 mm hot-rolled plate, cut to your length and width. Still, thicker sections depend on slab supply.
Can C-276 plate be welded without post-weld heat treatment?
Yes. Carbon at 0.010% max keeps grain-boundary carbides out of the weld zone, so post-weld heat treatment usually stays unnecessary. For that reason, shops save a furnace step on vessel fabrication.
Does hot forming change the delivered properties?
Hot work above roughly 650 °C can precipitate intermetallic phases, so a follow-up solution anneal restores corrosion resistance. In that case, tell us the forming route and we quote the re-anneal with the order.
Can you supply cut blanks, rings, and circles?
Yes. Plasma, waterjet, and shear cutting produce blanks, rings, and circles from any stocked gauge.
What is your MOQ for Hastelloy C-276 sheet?
A single plate or sheet covers most stocked gauges. Consequently, trial lots carry no premium hurdle.
What are your trade terms for Hastelloy C-276 plate?
FOB is the default Incoterm. Alternatively, EXW, CIF, and DAP quotes follow confirmed destinations.
How is Hastelloy C-276 plate priced?
We quote plate by weight in kilograms against the ordered gauge, width, and condition. The applicable Incoterm appears on every offer.
What is the lead time for Hastelloy C-276 plate?
Standard gauges ship in 7-15 days. Meanwhile, we quote cut-to-size or heavy plate against the confirmed schedule.
Do you provide EN 10204 3.1 or 3.2 certificates?
Yes. Each delivery carries an EN 10204 3.1 certificate. Likewise, we can arrange third-party 3.2 endorsement on request.
