We are Riddhi Siddhi Impex, an ISO 9001, ISO 14001, and ISO 45001-certified Mumbai-based Inconel Foils manufacturer and supplier established in 2002. We produce nickel-chromium superalloy foil to ASTM, ASME, and AMS standards. Inconel 600, 602, 625, 718 and Incoloy 800, 825, and 840 are in stock, holding a supply capacity of 400-500 tonnes monthly. Standard orders dispatch in 4-5 days. EN 10204 Type 3.1/3.2 mill certificates are available upon request.
Inconel foils are flat-rolled nickel-chromium superalloy products taken down to thin gauge, the material engineers specify when a part must keep its strength and surface stability through serious heat. Chromium grows a protective oxide film that repairs itself whenever service conditions strip it away, while the nickel matrix stays ductile and crack-resistant from cryogenic temperatures up into red heat. Fabricators convert the foil into combustion seals, bellows convolutions, heat shields, instrument diaphragms, thermocouple sheathing wraps, and furnace muffle linings. A component cut from a few grams of foil survives thermal cycling that would scale ordinary stainless steel away, which is why gas turbine and furnace builders keep the alloy family on their approved lists.
As a reliable Inconel foil supplier, all of the foils we offer passes through our slitting lines. We slit annealed source coil between 0.03 mm and 0.08 mm at our Mumbai and Taloja works, holding width to ±0.1 mm across the full 3 mm to 2000 mm range. We can drill inner diameters of 150 mm through 610 mm, build outer diameters as far as 1800 mm, and finish with a mill, slit, deburred, or round edge as specified. Heat-traceable certificates enter stock alongside the material, and pallet-packed wooden cases protect dispatches to the site or port.
7 grades we supply in our Inconel foil range, and each links to a dedicated page with complete composition and property data.
Inconel 600 foils combine excellent oxidation resistance with strong resistance to chloride stress corrosion cracking across industrial furnace sealing applications.
View gradeInconel 602 CA foils anchor a resilient alumina scale during extreme high-temperature thermal cycling, protecting critical muffle wrap fixtures.
View gradeMolybdenum-niobium alloying gives Inconel 625 foils high strength and exceptional pitting resistance against aggressive marine environments and acid condensates.
View gradePrecipitation-hardened Inconel 718 foils deliver supreme structural strength, serving as the industry standard for aerospace engine seals and spring elements.
View gradeIncoloy 800 foils resist high-temperature carburisation and oxidation, making them ideal for process piping and steam generation heat exchangers.
View gradeMolybdenum and copper additions let Incoloy 825 foils withstand aggressive reducing acids, localised pitting, and severe chloride stress cracking.
View gradeHigh-chromium Incoloy 840 foils provide superior scaling resistance up to 800 °C, optimised for electric heating elements and heat pipes.
View grade3 sectors consume most of the Inconel foil we slit. Temperature, process media, and strength requirements steer each one toward particular grades.
Engine programmes buy Inconel 718 Foils for seals, shims, and spring elements that must hold strength beside hot-section hardware, while Inconel 625 Foils serve exhaust and heat shield duty. AMS-grade material with full heat traceability matters here, and our documentation follows every slit coil we send.
Reactor lining wraps, gasket facings, and bellows in acid and chloride service lean on Inconel 625 Foils, with Inconel 600 Foils covering caustic and mixed alkaline streams. Plants hold slit foil against shutdown windows and dispatch in 4 to 5 days to restock them between turnarounds.
Furnace muffles, radiant shields, and fixture wraps cycle between ambient and bright red heat for years. Inconel 602 CA Foils own the hottest of this duty due to their alumina-forming chemistry, and Inconel 600 Foils handle the moderate zones at lower cost.
Paperwork travels with every consignment, from mill heat number to final dispatch note. Three ISO certifications stand behind that traceability at Riddhi Siddhi Impex.
Every order ships with an EN 10204 Type 3.1 mill test certificate tied to the original heat. Type 3.2 certification with independent witness inspection is arranged on request.
ISO 9001:2015 anchors our quality management system, from incoming source coil inspection through slitting and final gauge checks.
ISO 14001:2015 certifies our environmental management practices, including waste handling and material recovery across the works.
Occupational health and safety management on our shop floor and in our stores carries ISO 45001:2018 certification.
Inconel is a nickel alloy, so HS heading 7506 applies, the nickel flat-product heading that includes foil. Alloyed grades such as 600, 602, 625, and 718 take subheading 7506.20 rather than the stainless headings. Have your broker confirm the exact code for your destination.
Yes, Inconel 600, 602, 625, and 718, and Incoloy 800, 825, and 840 all remain stocked as soft annealed coil throughout the year, with 600 and 625 moving fastest. Standard dispatch takes 4 to 5 days, and urgent orders go out in 2 to 3.
Yes. We process Inconel foil from 0.03 mm to 0.08 mm thick and slit to any width from 3 mm to 2000 mm at ±0.1 mm.
As a trusted Inconel foil manufacturer based in Mumbai since 2002, we supply buyers across India and export to over 60 countries worldwide. Call or message us on WhatsApp, and a quote will reach you within 24 hours.
