Amigo Impex is a manufacturer, supplier, stockist and exporter of Hastelloy X sheets and plates, working from Mumbai, India, since 2013, with cutting, machining, fabrication, testing and packing done in-house.
Hastelloy X (UNS N06002) is a solid-solution-strengthened nickel-chromium-iron-molybdenum superalloy, and its flat-rolled forms anchor the high-temperature end of our Hastelloy sheets and plates range. Certification runs to ASTM B435 / ASME SB-435, with AMS 5536 answering aerospace sheet and plate callouts. Three alloying decisions define the chemistry. Chromium at 20.5–23.0% builds the oxide film that survives oxidising, reducing and neutral atmospheres up to 1,093°C (2,000°F). Molybdenum at 8.0–10.0% is the main solid-solution strengthener, and it is why the alloy keeps useful strength deep into the red-heat range rather than only near room temperature. Iron at 17.0–20.0% keeps Alloy X easy to form and weld.
Solution-annealed is the only condition we ship. Room-temperature testing under ASTM B435 requires 655 MPa (95 ksi) minimum tensile strength, 240 MPa (35 ksi) minimum yield strength and 35% minimum elongation. European and Asian drawings name the same metal 2.4665, NiCr22Fe18Mo or NW6002. Cold-rolled sheet runs from 0.5 mm to 3.2 mm and hot-rolled plate from 6 mm to 76 mm, cut to size before dispatch. Most consignments become gas turbine combustion components, industrial furnace internals and chemical process equipment. Supply covers pan-India, exports route to the USA, the Gulf, Europe and Asia, and pricing runs per kilogram in INR and USD. Every order leaves from Mumbai with a mill test certificate under our aerospace and pressure equipment approvals.
One table settles the routine checks on Hastelloy X sheets and plates: thickness bands, width and length limits, rolling routes, supply condition and edge options, with the governing standards tabulated separately below.
Flat-product documents alone govern this page. Bar, tube and wire specifications don't appear here, and each Hastelloy X sheet and plate certificate names the standard the lot was produced against.
| Standard | Scope |
|---|---|
| ASTM B435-22 | Heat and corrosion resistant high temperature alloy plate, sheet and strip |
| ASME SB-435 | ASME adoption of B435 for boiler and pressure vessel construction |
| AMS 5536 | Aerospace material specification for Hastelloy X sheet, strip and plate |
| ASTM B906 | General requirements and tolerances for nickel alloy flat products |
| DIN 17744 | Wrought nickel alloy composition standard covering NiCr22Fe18Mo (2.4665) |
Hastelloy X chemical composition balances a nickel base against chromium, iron and molybdenum, with cobalt and tungsten in minor roles. ASTM B435 sets these limits for UNS N06002 flat products.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | Remainder |
| Chromium (Cr) | 20.5–23.0 |
| Iron (Fe) | 17.0–20.0 |
| Molybdenum (Mo) | 8.0–10.0 |
| Cobalt (Co) | 0.50–2.50 |
| Tungsten (W) | 0.20–1.0 |
| Carbon (C) | 0.05–0.15 |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 1.00 max |
| Phosphorus (P) | 0.040 max |
| Sulphur (S) | 0.030 max |
ASTM B435 and ASME SB-435 standards require solution-annealed Alloy X sheets and plates to pass three room-temperature mechanical tests: tensile strength, yield strength, and elongation. Every test certificate logs these exact baseline figures.
Producer data rates the alloy's oxidation resistance to about 1,093°C (2,000°F). Above roughly 1,204°C (2,200°F), the high molybdenum content makes catastrophic oxidation a risk, so 2,000°F is the figure to design to. Hardness isn't given a B435 minimum, so the measured figure for each lot appears on its certificate.
| Property | Metric | Imperial |
|---|---|---|
| Tensile Strength, min | 655 MPa | 95 ksi |
| Yield Strength (0.2% offset), min | 240 MPa | 35 ksi |
| Elongation in 2 in. (50.8 mm) or 4D, min | 35% | 35% |
Overseas drawings name this metal under national designation systems rather than its trade name. The table states the designations of Hastelloy X sheets and plates we certify.
| Standard System | Designation |
|---|---|
| USA (UNS) | N06002 |
| Europe (W.Nr.) | 2.4665 |
| EN / DIN Chemical Symbol | NiCr22Fe18Mo (DIN 17744) |
| Japan (JIS H 4551) | NW6002 |
| China (GB) | GH3536 (formerly GH536) |
We at Amigo Impex provide our Hastelloy X flat product range in three supply types, each certified against the same specification before dispatch:
Gauge decides the packing. Interleaved sheets go into wooden cases with edge protection, while heavy plate is strapped onto skids as export-grade bundles. Every case carries grade, heat, size and specification marking alongside the invoice, packing list and certificate. Ready stock of Hastelloy X plates is dispatched from our Mumbai warehouse in 1 to 2 days; made-to-order material takes around 30 days. We supply both pan-India and overseas markets.
Amigo Impex holds AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certifications and tests every heat of Hastelloy X sheet and plate in-house. For the operations we perform in-house, we issue our own EN 10204 3.1; 3.2 witness certification and third-party inspection are arranged on request.
Hastelloy X plate price is calculated per kilogram and quoted at INR ₹2,550–₹5,100 per kg for domestic orders and USD 30–60 per kg for export. Nickel and molybdenum input costs set the base figure; thickness, sheet or plate form, rolling route, cut-to-size scope, quantity and the certification level ordered (ASTM B435 commercial or AMS 5536 aerospace release) settle the remainder.

Hastelloy X sheets are available from 0.5 mm to 3.2 mm thick and plates from 6 mm to 76 mm, in widths up to 1,524 mm and lengths up to 5,080 mm.
The standard draws the line at 4.76 mm (3/16 in.): under 4.76 mm, ASTM B435 calls the material sheet or strip, and 4.76 mm and over it calls plate. AMS 5536 uses the same split.
ASTM B435 and its ASME adoption SB-435, are the specifications Hastelloy X sheets and plates comply with; AMS 5536 applies when the order names an aerospace release.
Hastelloy X sheet and plate can be welded by GTAW, GMAW, SMAW and resistance methods, and the alloy cold forms readily for combustion-zone geometry.
About 1,093°C (2,000°F) is the practical maximum for continuous service in oxidising atmospheres for Hastelloy X Plates.
UNS N06002 is the same material as Hastelloy X sheet and plate. Trade shorthand HX or Hast X and the European number 2.4665 all resolve to this one alloy.
We supply Hastelloy X sheets and plates cut to size against drawing dimensions, and small-lot or single-piece orders run alongside bulk requirements.
Eight industries fabricate Hastelloy X plates and sheets into heat-facing components:
