MIDHANI's SN-41 Superalloy Promises to Revolutionize High-Temperature Applications in Jet Engines and Missiles

Mishra Dhatu Nigam Limited (MIDHANI), a leading Indian materials research and development organization, has achieved a significant breakthrough with the development of SN-41, a nickel-based precipitation hardening superalloy.

This new material exhibits exceptional properties that promise to revolutionize high-temperature and high-stress applications in critical sectors like aerospace and defence.

SN-41's robust characteristics make it an ideal choice for industries demanding high-performance materials. Its exceptional resistance to combustion gases, combined with superior strength and oxidation resistance at elevated temperatures, positions it as a crucial material for jet engine components and missile systems.

Here are the key features of SN-41:

• High-Temperature Strength: SN-41 maintains remarkable strength at temperatures up to 871°C (1600°F), enabling it to withstand the extreme heat generated within jet engines and during missile flights.
• Superior Oxidation Resistance: The alloy demonstrates outstanding oxidation resistance up to 982°C (1800°F), ensuring long-lasting performance and durability in harsh environments.
• Versatility: SN-41 is suitable for a wide range of critical applications, including turbine blades, wheels, combustion chamber liners, gas turbine nozzle partitions, petrochemical reactor components, fasteners, and missile components.

This development is a significant step forward for India's self-reliance in critical materials technology. By producing this superalloy domestically, India reduces its dependence on imports and strengthens its capabilities in strategic sectors.

SN-41 has the potential to play a crucial role in the development of advanced jet engines, like the Kaveri engine, and enhance the performance and reliability of missile systems.

Only I in the forum was continuously saying that for development of the afterburner section, BrahMos Aerospace, ISRO, GTRE & Midhani should come together to develop lightweight material that can withstand high temperatures for the Kaveri engine.

Jet engine temperature goes upto 1800° C. It is well below that level. How is it helpful?
