Ltd., Heavy Alloy Penetrator Plant, Composites Production Centre, Non-Ferrous Technology Development Centre, and the Advanced Research Centre International have followed the establishment of DMRL. The DMRL is also involved in R&D efforts to develop futuristic materials to provide advanced technology options.

Projects and products

DMRL has developed: * DMR 1700 Ultra-high-strength steel with the toughness combination equivalent to maraging steel; this steel has been used to build rocket motor casings for the Akash surface-to-air missiles * Jackal steel is an advanced grade high strength low alloy steel, The technology of Jackal steel has been passed on to Steel Authority of India Limited (SAIL) and MIDHANI for its bulk production. * Heavy alloy pre-fragments for Prithvi missile warheads developed for use against aerial targets *
