The Defence Metallurgical Research Laboratory (DMRL), a premier research laboratory of the Defence Research and Development Organisation (DRDO), has announced the successful transfer of technology for two critical steel products to ArcelorMittal Nippon Steel India Limited (AMNS India) in Surat.
This move aims to boost India's self-reliance in defence manufacturing by enabling domestic production of specialized steel previously reliant on imports.
The technologies transferred include DMR 249A steel sheets and plates, designed for naval applications, and DMR1700 mill forms, tailored for broader defence use.
DMR 249A is a low-carbon, micro-alloyed steel known for its exceptional toughness at sub-zero temperatures, a crucial property for warships operating in extreme conditions. However, the DMRL acknowledges that this steel grade has limitations in its corrosion resistance.
DMR1700, on the other hand, is a medium-carbon, low-alloy steel developed as a cost-effective alternative to maraging steel, often used in high-strength applications like missile casings and armored vehicles.
This technology transfer is expected to significantly enhance AMNS India's capabilities in producing high-grade steel that meets the stringent quality standards of the Indian Armed Forces.
By leveraging DMRL's expertise, AMNS India can ensure a consistent and reliable supply of these vital materials, reducing dependence on foreign suppliers and potentially lowering procurement costs.
According to DRDO's official website, DMR1700 steel is a result of extensive research spanning nearly two decades. It offers an ultra-high strength comparable to maraging steel but at a significantly lower cost, making it an attractive option for various defence applications.
