We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Inconel 602 Sheets & Plates, established in 2002. We stock Alloy 602 CA sheets from 0.8 mm and plates in heavier gauges to ASTM B168 / ASME SB-168. Our ISO 9001, 14001, and 45001-certified firm backs a monthly supply capacity of 400-500 tonnes, with EN 10204 Type 3.1 / 3.2 certificates available on request.
Inconel 602 sheets and plates are flat-rolled forms of a high-carbon nickel-chromium-iron alloy holding 24 to 26% chromium and 1.8 to 2.4% aluminium. The aluminium builds a dense alumina scale in hot air, anchored by small yttrium and zirconium additions. The grade resists oxidation to about 1200 °C and doesn't fade in carburising atmospheres. They are found in heat treatment equipment and furnace construction.
We stock cold-rolled Alloy 602 CA sheets from 0.8 mm and hot-rolled plates in heavier gauges, and 3 mm to 2000 mm wide. Material ships annealed to ASTM B168 with a mill test certificate on every order when requested.
We provide ASTM B168 Inconel 602 CA sheets and plates in annealed mill condition, with cold-rolled and hot-rolled finishes and three edge choices.

| USA (UNS) | N06025 |
| Europe (EN) | NiCr25FeAlY |
| Germany (W.Nr) | 2.4633 |
These 4 industries consistently use the Alloy 602 sheet and plate we supply, running equipment between 1000 °C and 1200 °C, where low-quality heat-resistant grades scale away.
Furnace builders use Inconel 602 sheet in muffles, retorts, radiant tube shields, and rollers for continuous annealing lines. The adherent alumina scale survives constant heating and cooling without spalling, so wall sections stay intact near 1200 °C instead of thinning year after year.
Hardening shops cut Alloy 602 CA plate into trays, baskets, grids, and fixture bases that ride through carburising furnaces daily. High carbon gives the grade its creep strength above 1000 °C, and the chromium-aluminium chemistry resists the carbon-rich atmosphere that embrittles standard fixtures.
Process engineers specify Inconel 602 CA plate for reformer internals, catalyst support grids, and heater components in ammonia, methanol, and hydrogen service. Metal dusting destroys many nickel alloys in these syngas streams; 602 CA resists it better than most flat-rolled materials.
Power plants and waste incinerators specify Alloy 602 sheet and plate around burners, combustion liners, ducting, and heat recovery sections. Burner hardware swings through wide temperature ranges every cycle, and the alloy's high carbon content holds creep strength at the top of that range while the alumina scale stays put through the swing.

Inconel 602 Sheets & Plates price in India is around ₹1,200 to ₹3,500 per kg. Export buyers generally pay $36 to $55 per kg. Nickel exchange rates set the base figure, and thickness, width, finish, and quantity move it. Dealer orders earn volume discounts; call or WhatsApp us for today's rate.
Inconel 602 CA sheets and plates contain 24.0 to 26.0% chromium, 8.0 to 11.0% iron, 1.8 to 2.4% aluminium, 0.15 to 0.25% carbon, and 0.05 to 0.12% yttrium, with the balance nickel.
We stock Alloy 602 CA sheets from 0.8 mm up to under 4.76 mm, and plates from 4.76 mm upward, in widths up to 2000 mm.
Alloy 602 CA plate and sheet are covered by ASTM B168 / ASME SB-168, the specification covering nickel-chromium-iron alloy plate, sheet, and strip.
INC 602 sheet serves in oxidising atmospheres up to about 1200 °C, one of the highest limits among wrought nickel alloys. The exact ceiling depends on the atmosphere and loading.
Cold-rolled sheets come in 2B or BA (bright annealed) finish. Hot-rolled plates are supplied annealed and pickled in the No. 1 condition. Mill, slit, or deburred edges come to order.
You can source Inconel 602 sheets and plates in India from us at Riddhi Siddhi Impex. Our Mumbai warehouse holds N06025 sheets and plates ready for dispatch. As a supplier, stockist, dealer, and exporter, we serve buyers across India and export worldwide, with quotes within 24 hours.
