Manufacturer, Supplier & Exporter of Inconel Shim (600, 625, 718)

Inconel Shims are precision-engineered thin sheets made from high-performance nickel-chromium-based alloys, such as Inconel 600, Inconel 625, and Inconel 718. These shims are specifically designed for applications that require exceptional resistance to heat, corrosion, oxidation, and extreme mechanical stress. Known for their outstanding thermal stability and strength at elevated temperatures, Inconel shims are widely used in aerospace, power generation, chemical processing, marine, and nuclear industries.

Riddhi Siddhi Impex is a leading Inconel Shim (600, 625, 718) domestic supplier and manufacturer in India, offering premium-grade Inconel shims in various thicknesses, tempers, and dimensions. With state-of-the-art processing facilities and quality control systems, the company ensures each shim sheet is manufactured to exact tolerances and meets international standards such as ASTM B168, B443, and B670. Their expertise in nickel alloys makes them one of the most trusted names in the high-performance metals industry.

The company manufactures Inconel shims in several popular grades. Inconel 600 offers excellent resistance to oxidation and carburization at high temperatures. Inconel 625 is highly resistant to aggressive environments including seawater, acidic and alkaline conditions. Inconel 718, on the other hand, provides exceptional strength and corrosion resistance while being suitable for cryogenic to elevated temperature applications. These materials are offered in soft annealed or cold-worked conditions, depending on the requirement

Riddhi Siddhi Impex supplies Inconel shims in precision thicknesses ranging from 0.05 mm to 3.00 mm, in forms such as foil, strip, sheet, and custom-cut shims. The surface finish can be customized to mill, bright, or polished finish, and all materials are traceable with material test certificates (MTC). Their shims are widely used in high-precision sealing, gasketing, thermal shielding, furnace linings, and critical aerospace assemblies.

The company’s reach as a domestic Inconel shim supplier extends to major metro cities like Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, and Ahmedabad, where industries such as oil & gas, automotive R&D, and chemical processing require high-performance materials. Riddhi Siddhi Impex offers fast delivery, technical support, and reliable supply to OEMs and maintenance contractors across these cities.
