DRDO to produce high nitrogen steel
Q. DRDO has signed a technology transfer agreement for manufacture of which steel?- Published on 03 Mar 17a. High nitrogen steel
b. Steel alloy
c. Both of the above
d. None of the above
ANSWER: Both of the above
The Defence Research and Development Organisation (DRDO) has signed a technology transfer agreement with Jindal Stainless (Hisar) Ltd. (JSHL) for manufacturing high nitrogen steel (HNS).
The steel alloy has significant applications in the defence sector, but currently the country is mostly dependent on imports.
HNS has higher ballistic strength and is not only tough but also has good strength.
It is non-magnetic and corrosion-resistant.
It costs about 40% less than that of rolled homogenous armour steel (RHA).
Its domestic production will further the Indian Army’s quest for lighter armouring material.
HNS: Know More- HNS is corrosion resistant and provides exceptional ballistic and blast protection than the existing material.
- This is at a much reduced thickness along with longevity which increases the fuel and mass efficiency.
- It exhibits higher energy absorption.
- Aim is to launch additional variants of HNS with enhanced blast and ballistic protection to cater to niche requirements of the defence sector.
- HNS passed ballistic tests in different calibers with 8-10 times higher impact and blast protection.
- 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.
