Mishra Dhatu Nigam (MIDHANI) is having production capacity to manufacture high nitrogen steel (HNS) for armour applications. This steel is planned to be produced in commercial scale as part of transfer of technology from Defence Metallurgical Research Laboratory (DMRL).
They have claimed that HNS is having better ballistic performance compared to the rolled homogenous armour steel.
This information was given by the Minister of State for Steel, Vishnu Deo Sai, in a written reply in the Lok Sabha.
DRDO has recognized that there has always been a demand to reduce the weight of armoured structures used in various ballistic applications. Weight reduction can be achieved by using newer materials having better ballistic performance or by changing the design of armour systems. Now, here enters the high nitrogen steel (HNS) for potential ballistic applications. DMRL has developed technology for production of high nitrogen steel (HNS) for armour applications and achieved improved ballistic performance compared to Rolled Homogenous Armour (RHA).
