Jindal Stainless forays into defense
High Nitrogen Steel is used in the manufacture of Light Infantry vehicles among others
Jindal Stainless (Hisar) Limited, country’s largest integrated stainless steel producer, on Wednesday announced its entry into the defense sector by signing the license agreement with Defense Research & Development Organisation (DRDO) for manufacturing high nitrogen steel (HNS) for armor applications.
With this, Jindal Stainless becomes India’s first company to commercially manufacture high nitrogen steel for the defense sector under the transfer of technology from DRDO. The use of HNS will replace the existing import of Rolled Homogeneous Armour (RHA), thereby resulting in improved cost efficiency in material acquisition for armor applications by 50 per cent, the company said in a statement.
The company is a comprehensive joint effort, and almost a decade of research and development by JSHL and Defense Metallurgical Research Laboratory (DMRL) to develop HNS. This major development will not only accelerate the indigenization process of Indian defense arsenal in line with government’s ‘Make in India’ drive but will also help in easy availability of best material for manufacturing lighter armor vehicles, as import procurement often delays the manufacturing process.
High Nitrogen Steel is corrosion resistant and provides exceptional ballistic/blast protection than the existing material at a much reduced thickness along with longevity which increases the fuel and mass efficiency. HNS exhibits higher energy absorption level, enhances crash worthiness to the entire artillery system and has significantly higher impact values (> 200 Joules at room temperature and > 150 Joules at -40C) as compared to RHA which make HNS a far superior material for blast protection. HNS has passed multiple levels of ballistic tests in different calibers with 8-10 times higher impact/blast protection.
HNS has potential application in all armored vehicles including Infantry Combat Vehicle (ICV), Light Specialty Vehicle (LSV), Light Armored Multipurpose Vehicle (LAMV), Futuristic Infantry Combat Vehicle (FICV), Main Battle Tank (MBT), Future Ready Combat Vehicle (FRCV), Aviation and Naval systems. JSHL is also working to produce additional variants of HNS with enhanced blast and ballistic protection to cater to niche requirements of the Indian Defense sector.
Abhyuday Jindal, Vice Chairman, Jindal Stainless (Hisar) Limited, said, “We believe HNS will immensely benefit the Indian defense sector, going forward. The hard-work and perseverance of 10 years of JSHL with Ministry of Defense has culminated in a fantastic result for the country in line with PM’s vision of Make in India.”
HNS is manufactured at JSHL unit at Hisar with triplex refining route and manufacturing process has already been optimized for industry scale production to cater to stringent and niche requirements of Indian defense and paramilitary forces. JSHL and DMRL together have developed the Quality Assurance Plan for the High Nitrogen Steel to ensure consistent quality to meet the future demand of HNS.
Jindal Stainless (Hisar) is India's first stainless steel manufacturing unit. JSHL has its operations integrated, both backward and forward, starting from melting, casting, hot rolling to cold rolling and other value additions. JSHL has a melt capacity of 8,00,000 TPA, one of the largest in India. It is also the world's largest producer of stainless steel strips for razor blades and India's largest producer of coin blanks, serving the needs of Indian and international mints.
