DRDO’s DMRL Hyderabad & Jindal Stainless Ltd signed Transfer of Technology (ToT) agreement on High Nitrogen Steel for Armour Appns on Wednesday
New Delhi: The country’s largest stainless steel maker Jindal Steel (Hisar) (JSHL) marked its sortie into Defence sector by a pact with DRDO for transfer of technology connecting to high-nitrogen steel for armour applications on Wednesday.
“The use of high-nitrogen steel will replace the existing import of Rolled Homogeneous Armour (RHA), resulting in, to improve cost efficiency in material acquisition for armour applications by 50 per cent,” JSHL said after the pact has signed in the presence of Minister of State for Defence Subhash Bhamre.
Addressing to the event, Bhamre said that it is a breakthrough technology for armour applications and boosts up to indigenous technologies, in line with the Prime Minister Narendra Modi’s ‘Make in India’ vision.
Terming pack as a “comprehensive” joint effort, JSHL has said it took almost a decade of R&D by JSHL and Defence Metallurgical Research Laboratory (DMRL) to develop high-nitrogen steel (HNS).
“This will usher in self-reliance and global leadership in Defence,” Bhamre said, urging the industry to explore for further up gradation of technology.JSHL said it forayed into the Defence sector by “signing the license agreement with the Defence Research and Development Organisation (DRDO), Ministry of Defence, which entails the transfer of technology for manufacturing HNS for armour applications”.
Elaborating, JSHL claims to be the India’s first company to commercially manufacture HNS for the Defence sector.
The company also said this development will not only just accelerate the indigenisation process of the Indian Defence arsenal in line with ‘Make in India’, but help in easy availability of best material for manufacturing lighter armoured vehicles as import procurement often delays the manufacturing process. HNS is corrosion resistant and provides the exceptional ballistic and blast protection than the existing material at a much-reduced thickness along with longevity which increases the fuel and also mass efficiency.
It exhibits higher energy absorption level which enhances crashworthiness to the entire artillery system and has significantly higher impact values with a far superior material for blast protection.
“HNS has passed multiple levels of ballistic tests in different calibres with 8-10 times the higher impact and blast protection,” the company said. It is said that it has potential application in all armoured vehicles, including infantry combat vehicle (ICV), light speciality vehicle (LSV), light armoured multi-purpose vehicle (LAMV), futuristic infantry combat vehicle (FICV), main battle tank (MBT), future ready combat vehicle (FRCV), aviation and naval systems.
The company said it is also working to produce additional variants of HNS with an enhanced blast and ballistic protection to cater to niche requirements of the Defence sector.
