DMRL has also transferred the manufacturing technology for DMR-249A and DMR-249BK grade steel billets to ASP, Durgapur for use in the construction of naval ships and submarines.

The technology transfer agreement has been handed over by DRDO officials to SAIL representatives at Hyderabad on July 21. Subsequently, the LAToT documents were formally handed over to RSP Executive Director (Works) B. R. Palai at a function held at the plant on July 29.

Developed indigenously by DMRL, DMR-249B is a high-strength, low-alloy structural steel designed for naval shipbuilding. The steel offers a high strength-to-weight ratio, enabling lighter and more resilient hull structures for warships, submarines and other combat vessels while reducing dependence on imports, SAIL said in an official statement.
