We are Riddhi Siddhi Impex, a Mumbai-based Inconel 602 Shims manufacturer and supplier, established in 2002. Our slitting lines produce Alloy 602 CA (UNS N06025) shim stock to ASTM B168 / ASME SB-168, from 0.03 mm to 5 mm thick, with width held to ±0.1 mm. Our ISO 9001, 14001, and 45001-certified company backs ready stock with a supply capacity of 400-500 tonnes monthly. We also provide EN 10204 Type 3.1 / 3.2 certificates on request.
Inconel 602 shims are precision spacers slit from a nickel-chromium-iron alloy carrying 24.0 to 26.0% chromium, 1.8 to 2.4% aluminium, and a high 0.15 to 0.25% carbon. The carbon forms carbides for creep strength, while chromium and aluminium grow a protective alumina-rich scale that yttrium and zirconium anchor through thermal cycling. Our high-performance Inconel 602CA Shims are typically used as high-temperature joint spacers, sealing shims, and wear plates inside industrial furnaces, gas turbines, and chemical reactors. The result is an Inconel shim that keeps its shape and surface at service temperatures up to 1200 °C. Typical uses include heat treatment furnaces, radiant tubes, petrochemical processing units, kiln systems, thermal oxidizers, incinerators, and high-temperature sealing assemblies.
As a reliable Alloy 602CA Shims supplier, we slit Nickel Alloy 602 CA shim stock from inconel coil in soft annealed condition to ASTM B168. Buyers choose any width from 3 mm to 2000 mm, three finishes, and three edge options; every consignment carries a mill test certificate, with EN 10204 Type 3.1 / 3.2 documents on request.
We provide Inconel 602CA shims in soft annealed condition to ASTM B168 / ASME SB-168, precision-slit to the dimensions, finishes, and edges tabulated below.

Carbon separates this grade from other heat-resistant nickel alloys. At 0.15 to 0.25%, it forms chromium-rich carbides that hold creep strength close to the alloy's melting range.
| Element | Composition (%) |
|---|---|
| Chromium (Cr) | 24.0 to 26.0 |
| Nickel (Ni) | Balance |
| Iron (Fe) | 8.0 to 11.0 |
| Carbon (C) | 0.15 to 0.25 |
| Aluminium (Al) | 1.8 to 2.4 |
| Titanium (Ti) | 0.10 to 0.20 |
| Yttrium (Y) | 0.05 to 0.12 |
| Zirconium (Zr) | 0.01 to 0.10 |
| Silicon (Si) | 0.50 max |
| Manganese (Mn) | 0.15 max |
| Copper (Cu) | 0.10 max |
Annealed Alloy 602CA shims meet a 675 MPa minimum tensile strength with 30% elongation per ASTM B168. The yield minimum applies at 0.508 mm and above; figures for thinner shim gauges are indicative.

These 3 industries use most of the Inconel 602 CA shims we slit, because the grade remains oxidation resistant where most heat-resistant alloys scale away at extreme furnace temperatures.
Furnace builders pack Inconel 602 shims under burner mounts, radiant tube hangers, and fixture bases exposed to direct flame radiation. The alumina scale resists spalling through repeated cycles near 1200 °C, so shimmed joints stay tight between rebuilds. Annealing cover plates and muffle supports take the same material.
Reformer and cracker maintenance crews set flange gaps and align pump bases with Nickel Alloy 602CA shims in carburising service. Metal dusting destroys conventional heat-resistant grades in syngas plants; high chromium and aluminium content significantly slows that attack. Shims hold their measured thickness, so alignment survives shutdown cycles.
Power stations and emission-control fabricators fit Alloy 602 shims in burner assemblies, turbine housings, and hot flue duct joints. The grade keeps working strength at high heat and minimizes oxide spallation into downstream catalysts. Gauges from 0.03 mm let technicians correct clearances in fine steps.
