We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Inconel 602 Coils, established in 2002. Our Alloy 602 CA coil stock meets ASTM B168/ASME SB-168 standards, with gauges ranging from 0.03 to 5 mm and slit widths of 3 to 2000 mm with ±0.1 mm tolerance. Our ISO 9001, 14001, and 45001-certified company holds a 400-500-tonne monthly supply capacity. EN 10204 Type 3.1 / 3.2 certificates on request.
Inconel 602 coils are wound lengths of flat-rolled 602 CA, a high-carbon nickel-chromium-iron alloy built for extreme heat. An aluminium scale which sustains cyclic service near 1200°C is produced by chromium of 24 to 26% combined with 1.8 to 2.4% aluminium. A small yttrium addition keeps that scale anchored. Density is 7.93 g/cm³, and resistance to carburisation and metal dusting completes the grade. Inconel 602 coils are typically used in furnace muffles, thermal processing equipment, chemical processing, and exhaust systems.
We stock these coils rather than roll them, sourcing Inconel coils from established primary mills. Our slitting lines cut any width from 3 mm to 2000 mm, and material leaves solution-annealed to ASTM B168 with a mill test certificate on every order upon request, in the finish and edge you specify.
We provide ASTM B168 Inconel 602 Coils in solution-annealed condition, two surface finishes, and four edge options, slit to width from ready stock in hot rolled and cold rolled forms.

UNS N06025 coils hold 0.15 to 0.25% carbon, which contributes to the carbide strengthening responsible for the grade's excellent creep resistance, while chromium and aluminium handle oxidation.

Solution-annealed Alloy 602 coils meet a 675 MPa minimum tensile strength with 30% elongation, so they slit and press cleanly before hardening in service. Yield minimums apply from 0.508 mm up; thinner gauges stay indicative.

These 3 industries consume most of the Inconel 602 CA coils we supply. Each picks the grade for oxidation life above 1000°C, where low-cost heat-resistant alloys scale away.
Furnace fabricators roll our IN602 coil stock into muffles, radiant tube shells, and retort sections. Because the alumina scale doesn't spall under repeated heating and cooling, wall sections keep their thickness near 1200 °C. Slit-to-width coil feeds forming lines directly and cuts scrap on long production runs.
Hardening shops build baskets, trays, belt links, and quench fixtures from Alloy 602 CA coils. Carrier hardware faces carburising atmospheres that load stainless fixtures with carbon until they crack. The 602 CA grade resists that pickup and keeps its creep strength through years of cycling above 1000 °C.
Process plants specify Inconel 602 coils for reformer internals, catalyst support grids, and strip-formed parts in ammonia, methanol, and hydrogen service. Metal dusting is the main threat in these syngas streams. High chromium and aluminium levels block it, so components outlast conventional heat-resistant grades several times over.
As an Inconel 602 coils exporter, we pack in wooden cases or on pallets and dispatch globally to most of the countries from Mumbai.
