State-owned Mishra Dhatu Nigam Limited (MIDHANI) has announced a significant breakthrough in the development of Inconel 718, a high-end superalloy critical for advanced aerospace applications. This alloy, considered one of the most challenging materials to manufacture, is pivotal for the development of aero engines and other strategic technologies in India.
Inconel 718 is widely regarded as one of the most difficult alloys to produce, particularly due to its high strength, resistance to extreme temperatures, and demand for stringent quality standards. MIDHANI has successfully developed a version of this alloy with a 325 mm diameter (over 12 inches), achieving exceptional quality standards and minimal defect levels of just 1.2 mm, a remarkable accomplishment in the field of metallurgy.
The development of Inconel 718 supports several key programs, including Kaveri Dry Engine (ATDG), Small Turbo Fan Engine (STFE).
The successful development of Inconel 718 highlights MIDHANI’s growing expertise in advanced material science and its critical role in India’s Make in India initiative. This milestone not only reduces dependence on imports for high-end alloys but also strengthens India’s ability to produce cutting-edge aerospace and defense technologies indigenously.
