Operating from Mumbai since 2013, Amigo Impex is an Incoloy 825 bars and rods manufacturer and supplier serving processing plants across India, along with export markets in the USA, the Gulf, Europe, and Asia. We manufacture and stock UNS N08825 bar to ASTM B425 and ASME SB-425, with cutting, machining, threading, and testing handled in-house before dispatch.
Incoloy 825 is a nickel-iron-chromium alloy carrying molybdenum, copper, and titanium additions. That chemistry withstands sulphuric and phosphoric acids, resists chloride stress-corrosion cracking, and holds off pitting in crevice-forming geometries. Annealed bar delivers a minimum tensile strength of 586 MPa with 30% elongation, so machined shafts and studs retain ductility alongside strength.
European drawings identify the same material as W.Nr. 2.4858, and our stock spans round bar from 3 mm to 800 mm in diameter, plus hex, square, flat, rectangular, and forged profiles in lengths up to 6 metres. Pump shafts, valve stems, and agitator components machined from this bar are used in oil and gas, chemical, marine, and nuclear fuel processing services. Export packing, heat-number traceability, and per-kg pricing in INR or USD complete the supply scope. Amigo Impex holds AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certifications, and every consignment leaves with a mill test certificate.
A purchase order for Incoloy 825 round bar should include the key specification details to ensure the material is supplied correctly and meets the required standards for the application.
Bar and Incoloy 825 rod in UNS N08825 are ordered against a short list of governing documents. Designation systems such as W.Nr. 2.4858 aren't standards; they appear under Equivalent Grade instead.
| Standard | Scope |
|---|---|
| ASTM B425 | Ni-Fe-Cr-Mo-Cu alloy (UNS N08825) rod and bar |
| ASME SB-425 | Boiler and Pressure Vessel Code adoption of ASTM B425 |
| DIN 17752 | European standard for nickel alloy rod and bar (2.4858) |
Molybdenum at 2.5- 3.5% and copper at 1.5 - 3.0% supply Alloy 825 bar for reducing acids such as sulphuric and phosphoric, while titanium stabilises the grade against intergranular attack.
| Element | Weight % |
|---|---|
| Nickel (Ni) | 38.0 - 46.0 |
| Chromium (Cr) | 19.5 - 23.5 |
| Iron (Fe) | 22.0 min |
| Molybdenum (Mo) | 2.5 - 3.5 |
| Copper (Cu) | 1.5 - 3.0 |
| Titanium (Ti) | 0.6 - 1.2 |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 0.5 max |
| Carbon (C) | 0.05 max |
| Aluminium (Al) | 0.2 max |
| Sulphur (S) | 0.03 max |

Ready stock held by Amigo Impex as a stockist spans every profile listed here, and it's sheared or sawn in-house to cut lengths from 100 mm.
| Profile | Dimension | Range |
|---|---|---|
| Round Bar | Diameter | 3 - 800 mm |
| Round Bar | Threading stock | M6 - M48; 1/4 in - 2 in |
| Hex Bar | Across flats (A/F) | 2 - 180 mm |
| Square Bar | Side width | 2 - 200 mm |
| Flat Bar | Thickness | 3 - 100 mm |
| Flat Bar | Width | 10 - 300 mm |
| Rectangular Bar | Thickness x Width | 2 - 100 mm x 10 - 500 mm |
| All Profiles | Length | 0.5 - 6.0 m; cut lengths from 100 mm |
Profile choice follows the component: hex bar feeds fastener machining, flat bar suits wear strips. We supply 6 forms in this grade.
Bars leave our Mumbai stockyard in bundles, wooden crates or pallets, each marked with grade, size, specification and heat number. Export consignments clear through port on FOB, CIF or CFR terms. As an Incoloy 825 bars and rods exporter, we match packing to the destination, and urgent domestic dispatches move within 1-2 days.
Three checks run in-house on every heat: chemical analysis, tensile testing and hardness. Third-party inspection is arranged on request. Mill test certificates to EN 10204 3.1 or 3.2 accompany each order, drawn from the original mill or from our own testing.
Incoloy 825 bars and rods price per kg moves with five variables: nickel raw-material rates, bar profile, diameter band, surface finish and order weight. The price in India is ₹1,400 – ₹3,100 and US$16 – US$37 per kg. We quote INR per kg domestically and USD per kg for export orders.

Incoloy 825 round bar is a Ni-Fe-Cr-Mo-Cu alloy bar supplied to ASTM B425 in grade UNS N08825. Chemical processing, oil and gas, marine and nuclear fuel plants machine it into components that face acids, chlorides and seawater.
Yes. Both names refer to UNS N08825, though Inconel 825 isn't strictly correct: Incoloy is the proper family name, while Inconel covers a separate nickel-chromium group.
UNS N08825 is the American designation for Incoloy 825 bar, and W.Nr. 2.4858 under DIN 17752 is the European equivalent. Japanese drawings cite NCF 825; British ones use NA 16.
No noticeable magnetism shows in the annealed condition: the austenitic structure keeps Incoloy 825 round bars non-magnetic.
The typical hardness of Incoloy 825 bars ranges from 135 to 165 HB; the measured hardness of these bars and rods is reported on the mill test certificate.
The rapid work-hardening of Incoloy 825 round bar makes it demanding to machine, since the skin hardened by one pass resists the next. Machining runs on solution-annealed stock, with external threads cut by single-point lathing or formed by thread rolling.
The Per-kg rates for Incoloy 825 round bar in India range from ₹1,400 to ₹3,100 and US$16 to US$37 per kg. Prices may vary depending on size, material, market value and other factors.
Machined into shafts, stems, studs and springs, alloy 825 round bar serves these eight industries.
