Defence Metallurgical Research Laboratory (DMRL), Hyderabad and Jindal Stainless (Hisar) Limited (JSHL) on 1 March 2017 signed the Licensing Agreement for Transfer of Technology of High Nitrogen Steel (HNS) for armour applications. DMRL is a premier research laboratory of Defence Research and Development Organization (DRDO).
The High Nitrogen Steel (HNS) technology is a step forward towards Army’s quest for lighter and high-performance armouring material as compared to materials that are used at present. Apart from its use in Army’s armouring, HNS has the potential of being used in numerous civilian applications.
Minister of State for Defence, Dr Subhash Bhamre who congratulated both DRDO and DMRL for the achievement also called upon both public as well as private Industries and Ordnance Factories to use this material extensively in their products.
About High Nitrogen Steel
• HNS is tough material and has good strength.
• It is non-magnetic as well as corrosion resistant
• It cost is about 40 percent less compared to Rolled Homogenous Armour Steel (RHA).
• This material has the potential for a number of defence and civil applications like armouring, mine trawls, oil industries among others.
At present, the HNS technology is available with very few countries of the world.
