In a significant advancement for India’s aerospace industry, Mishra Dhatu Nigam Limited (MIDHANI), in collaboration with Hindustan Aeronautics Limited (HAL), showcased a breakthrough at Aero India 2025. Sudhanshu Mohan Jena, Executive Director of HAL Koraput, and Shri A.K. Sharma, General Manager (Marketing) of MIDHANI, unveiled the newly developed SuperNi 41 plates, an indigenous high-performance material tailored for aero engine applications.
Known as SuperNi 41, this material is a precipitation-hardenable nickel-chromium base superalloy. It boasts exceptional strength retention at temperatures ranging from 649°C to 982°C, making it ideal for environments where thermal loads are extreme. Its design caters to severely stressed components that require superior corrosion and oxidation resistance.
SuperNi 41 is among the select few superalloys that pose significant challenges during hot working due to its narrow thermal mechanical processing range. Its mechanical properties are highly dependent on precise heat treatment parameters, and it has poor machinability. MIDHANI has mastered the optimization of process parameters, ensuring the alloy meets stringent customer requirements in both properties and dimensions.
SuperNi 41 is engineered for critical components in jet and rocket engines, as well as for high-speed airframe parts like turbine casings, wheels, buckets, and torque rings Where resilience to high thermal stress is paramount.
The development of SuperNi 41 by MIDHANI marks a milestone in India’s journey towards self-reliance in aerospace materials. This grade not only enhances the capability of domestic manufacturers like HAL to produce high-performance engines and components but also reduces reliance on imported materials, thereby bolstering national security and economic self-sufficiency.
