We are Riddhi Siddhi Impex, an ISO 9001, ISO 14001, and ISO 45001-certified Hastelloy Foils manufacturer and supplier operating from Mumbai since 2002. Our lines slit Ni-Cr-Mo alloy foil down to 0.03 mm against ASTM B575 / ASME SB-575. Supplying a capacity of 400 to 500 tonnes per month, with dispatch inside 4 to 5 days, keeps plant maintenance and OEM production moving. We also provide EN 10204 Type 3.1 / 3.2 mill test certificates on request.
Hastelloy alloy foil is a high-performance, thin-gauge flat product rolled from a specialised nickel-chromium-molybdenum blend, the material chemical engineers reach for when stainless steel gives up. Molybdenum defends the metal in reducing acids, chromium guards it in oxidising ones, and together they shut down the chloride pitting and crevice attack that damages austenitic grades in hot brines and acid condensates. At foil gauge, this corrosion resistance goes where heavier strip cannot: gasket facings, seal windings, bellows convolutions, instrument diaphragms, and lining wraps for reactor internals. A part weighing a few grams then protects equipment worth crores, which is why buyers accept the alloy's premium over stainless without much argument.
As a reliable Hastelloy foil supplier, our Mumbai and Taloja warehouses have annealed soft source coil, slit in-house between 0.03 mm and 0.08 mm. Edge condition follows the order: slit, deburred, round, or mill. Heat-traceable mill documentation accompanies each coil into stock, and wooden cases with pallet packing carry the finished foil to the site or port.
We manufacture Hastelloy foils in 2 grades, C276 (UNS N10276) and C22 (UNS N06022), both stocked in the annealed condition to ASTM B575. Chromium content splits their duties, and it decides which grade belongs in strongly oxidising services.
Versatile UNS N10276 foil resists shifting mixed acids, making it perfect for gaskets, reactor linings, and heat exchangers.
View gradeChromium-rich UNS N06022 foil resists wet chlorine gas and oxidising acid mixtures, outperforming C276 in scrubber components.
View grade3 industrial sectors utilise the Hastelloy foil produced by our slitting lines. Whether the process media is lean oxidising or reducing settles the choice between C276 and C22.
Acid plants and speciality chemical units wrap gasket facings, seal windings, and reactor lining foil from Hastelloy C276, because feed streams there rarely stay purely oxidising or purely reducing for long. Maintenance teams hold slit foil against shutdown schedules, and our 4 to 5 day dispatch feeds those windows from ready stock.
Flue gas desulphurisation ranks among the harshest duties in industry: hot, chloride-laden, oxidising condensate attacks scrubber internals continuously. Hastelloy C22 foil serves here as sealing and lining material, its chromium-rich chemistry built for exactly this acid-gas environment. Absorber and damper seal fabricators order it slit to width.
Reactor and vessel builders in pharma pick Hastelloy foil for gaskets and sanitary sealing elements that face aggressive intermediates and repeated cleaning chemistry. C276 handles the broad run of process media, while lines cleaned with oxidising agents move up to C22. Heat-level traceability travels with every slit coil we send.
Documentation follows each Hastelloy foil consignment from mill heat through dispatch. Riddhi Siddhi Impex holds three ISO certifications on top of that traceability.
An EN 10204 Type 3.1 mill test certificate is traced to the original heat sheets with every order. Type 3.2 with a third-party witness comes on request.
Our ISO 9001:2015 certification governs the quality management system across rolling, slitting, inspection, and dispatch, with gauge and width checks logged per order.
ISO 14001:2015 directs our environmental management, from coil storage through processing and scrap recovery.
Workplace health and safety across the warehouse and foil lines runs under ISO 45001:2018.
Hastelloy foils fall under HS heading 7506, covering nickel plates, sheets, strip, and foil. Alloyed material such as C276 and C22 ships under subheading 7506.20, not the stainless headings 7219 or 7220. Confirm the final code with your customs broker.
Yes, both grades stay in ready stock as annealed mother coil through the year, with C276 moving faster. Dispatch runs 4 to 5 days as standard; urgent orders go out in 2 to 3.
Yes. Our lines process Hastelloy foil from 0.03 mm to 0.08 mm thick and slit any width between 3 mm and 2000 mm, holding ±0.1 mm.
As a premier Hastelloy foil manufacturer, Riddhi Siddhi Impex has produced and stocked high-quality foils in Mumbai since 2002, serving buyers across India and exporting to 60+ countries. Call or WhatsApp our team and your quote lands within 24 hours.
