Used for bullet proofing of civilian vehicles and that of security personnel, such steel has either been manufactured under restrictive technology transfer agreements with foreign countries, or simply imported into India. There is a good and growing potential for this product as it can be used in light armored vehicles and protective shields or structures. Today, manufacturing bullet proof steel requires a highly specialised technology.

The specialised steel in bullet proofing of vehicles would not only reduce India's dependence on imported steel but also cut foreign currency outgo with possibility of balancing price quotes.

The newly-developed bullet proof steel at ESIL absorbs the impact of bullets traveling at a speed of 700 m/sec, with barely a dent on the surface. This steel has hardness levels above 500 (Brinell hardness number) BHN and is extremely tough. Ballistic performance of this product was successfully tested in India and in Germany at the Gujarat Forensic Science Laboratory (FSL), as well as at IABG, an internationally-renowned German laboratory.

Being the existing supplier of specialised grade steel like DMR 249A grade, a special steel for building warships, from its Hot Strip Mill since 2001, ESIL continues its legacy with India's defense sector.

After commissioning of its 5 metres wide plate mill with sophisticated heat treatment facilities in 2009, several new grades were developed and the product range for the existing grades was enhanced.

Meanwhile, the company has collaborated with the defense sector to produce grades like CDA-99, EN10025-6-S690QL, very tough steels used in heavy armored vehicles. However, the crowning glory has been the production of DMR-1700, an ultra-tough steel of yield strength 1500 Mega Pascal, designed by Defense Research Development Organization (DRDO). All of these products had been stabilised and commercialised through dedicated in-house research and development (R&D) and operations efforts of its engineers.

DMR 1700 steel developed by DMRL-DRDO, ToT given to Essar

India's DMR 1700 special steel alloy ready for commercial use (2011)

Syed Akbar
Hyderabad, Nov 15: A special steel alloy, DMR 1700, with ultra high
strength, developed by the city-based Defence Metallurgical Research
Laboratory (DMRL) and Mishra Dhathu Nigam (Midhani), is all set for
commercial production. This steel alloy will bring down the cost of
missiles and rockets by as much as two-thirds.


Dr VK Saraswat, scientific advisor to the defence minister, said the
DMR 1700, developed a few years ago, is all set to replace the 250
grade maraging steel, which is now used in missiles and rockets. “Once
DMR 1700 is used in missiles and rockets, the cost will come down by
about 60 per cent,” he said. Dr Saraswat was in the city to
participate in the ongoing 65th annual technical meeting of the Indian
Institute of Metals (IIM).


DMR 1700 is an advanced material that could boost the country’s weapon
systems and military hardware. It is a low-alloy steel with ultrahigh
strength and high fracture toughness. The DRDO developed it as a cost
effective replacement of 250 grade maraging steel, now currently used
in aerospace applications in the country. It will also bring down the
cost of launch vehicles.

As a corrosion-proof alloy, DMR 1700 can also be used for ship hulls
in the Navy.
“The production will begin shortly,” he told reporters,
adding that it is as strong as the maraging steel. Metallurgical
standard tests have been completed on this special steel alloy. Dr
Saraswat emphasized the need for a certification centre for metals in
the country.

Referring to production of rare earth elements like zircon and
monazite, Dr Saraswat said the Indian Rare Earths Limited would step
up its production to gain self-sufficiency in the field. “We have
earlier stepped down the production as production of rare earths was
uneconomical. However, China has now gained the world leadership in
production of rare earth metals using monazite sands. We are stepping
up the production in the area using beach sands,” he added.

Why ESSAR? The Ruias are the most corrupt business family in the county.

No they are least corrupt but they are not so smart as others so their corruption gets exposed very quickly.

COngratulation to Essar and mishra Dhatu nigam limited.
