We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Incoloy 825 Coils, established in 2002. We hold a ready stock of nickel-iron-chromium alloy coils to ASTM B424 / ASME SB-424 from 0.03 mm to 5 mm. Our ISO 9001, 14001, and 45001-certified company carries a monthly supply capacity of 400 to 500 tons and ships with EN 10204 Type 3.1 / 3.2 mill test certificates.
Incoloy 825 coils are flat-rolled nickel-iron-chromium products alloyed with molybdenum, copper, and titanium. The high nickel content resists chloride stress corrosion cracking, while molybdenum and copper give the grade its resistance to reducing acids such as sulphuric and phosphoric. Chromium handles oxidising media. Titanium stabilises UNS N08825 coils against sensitisation after welding.
We supply these coils from ready stock, buying parent coils from reputed primary mills and processing them in-house to the required width. Material ships in the annealed mill condition, in 2B, BA, HR pickled, or CR finish, with deburred, mill, or slit edges and test documentation on request.
We provide ASTM B424 Alloy 825 coils in the annealed condition, across several finishes and edge options, slit to width from ready stock in hot rolled and cold rolled forms.

Nickel defines this grade at 38 to 46%, which resists chloride stress corrosion cracking. Molybdenum and copper together carry the resistance to sulphuric and phosphoric acid, and titanium ties up carbon to stabilise welds, as the ASTM B424 composition below shows.
| Element | Composition (% by weight) |
|---|---|
| Nickel (Ni) | 38.0 to 46.0 |
| Iron (Fe) | 22.0 min |
| Chromium (Cr) | 19.5 to 23.5 |
| Molybdenum (Mo) | 2.5 to 3.5 |
| Copper (Cu) | 1.5 to 3.0 |
| Titanium (Ti) | 0.6 to 1.2 |
| Carbon (C) | 0.05 max |
| Manganese (Mn) | 1.0 max |
| Silicon (Si) | 0.5 max |
| Sulphur (S) | 0.03 max |
| Aluminium (Al) | 0.2 max |
Annealed Alloy 825 coils reach a minimum tensile strength of 586 MPa with 30% elongation, so they form, roll, and deep-draw without cracking. Coils ship in the standard mill condition only.

| Germany (W.Nr) | 2.4858 |
| Japan (JIS) | NCF 825 |
| United Kingdom (BS) | NA 16 |
These 4 industries take most of the Nickel Alloy 825 coils we supply. Buyers select the grade for resistance to reducing and oxidising acids, immunity to chloride stress corrosion cracking, and stability after welding.
Chemical plants form Incoloy 825 coils into tanks, evaporators, and pickling equipment that handle sulphuric and phosphoric acid. The copper and molybdenum content holds the alloy stable in reducing acid service, where plain stainless grades pit and lose section.
Sour-service operators specify Alloy 825 coils for downhole tubulars, separators, and wellhead components exposed to hydrogen sulphide and chloride brines. The nickel base resists stress corrosion cracking, and the titanium stabilisation keeps welded joints reliable in hot, corrosive wells.
Marine and flue-gas plants press 825 coils into heat exchangers, scrubber linings, and seawater handling parts. The grade shrugs off chloride pitting and crevice attack, so scrubber internals survive acidic condensate and salt-laden gas that corrodes austenitic stainless steel.
Reprocessing plants choose Incoloy 825 coils for equipment that contacts hot nitric and mixed acids. The chromium content builds oxidation resistance for the nitric side, while the balanced chemistry resists intergranular attack under acid cycles.

Incoloy 825 Coils price in India is around ₹1,418-₹1,800 per kg. For international buyers, it works out to roughly US$45-$68 per kg. The rate tracks nickel and molybdenum benchmarks, and thickness, width, finish, and volume all move the figure. Volume discounts apply to bulk orders, so call or WhatsApp us for today's rate.
We supply Incoloy 825 coils as per ASTM B424 / ASME SB-424 for coil, plate, sheet and strip. Coils are shipped in annealed mill condition. EN 10204 Type 3.1 / 3.2 mill test certificates are available on request.
We supply Incoloy 825 coils in thicknesses from 0.03 mm to 5 mm and widths from 3 mm to 2000 mm, with coil ID from 150 mm to 610 mm and coil OD up to 1800 mm. Custom widths are slit at ±0.1 mm.
Incoloy 825 coils are of two types, HR and CR, which differ in rolling route and gauge. HR coils are hot rolled, annealed and pickled in heavier gauge. CR coils are cold rolled to thinner gauge with tighter tolerances and smoother 2B or BA finishes.
The price of Incoloy 825 coils is around ₹1,418-₹1,800 per kg, roughly US$45-$68 per kg for export buyers. Thickness, width, finish, quantity, and prevailing nickel rates all shift the figure, so contact us for a firm quote.
Incoloy 825 coils are used in chemical processing, oil and gas, marine, pollution control, and nuclear fuel reprocessing, wherever resistance to sulphuric, phosphoric, and nitric acids and to chloride stress corrosion cracking is essential.
