New special grade steel for indian Submarines
Alloy Steels Plant
(ASP) –alloy and special steels arm of the Maharatna steel giant Steel
Authority of India Limited (SAIL) has successfully made DMR-292A grade
steel for the first time for Indian Navy based on specifications
indigenously developed by DMRL (DRDO). This high-strength & low
temperature impact toughness grade steel will be used for making
submarines. The steel was made in presence of senior scientists from
DMRL, Hyderabad and engineers of ASP, Durgapur. The steel will be
processed to plates through Rourkela Steel Plant (RSP) directly or via
Bokaro Steel Plant before supply to DMRL for further testing as quoted
SAIL officials. The process would be then ready for certification. Once
stabilized, the commercial production of this grade at ASP shall
definitely give SAIL a shot in the arm. ASP enjoys stable partnership
with Defence establishments. Last year, ASP successfully supplied
DMR-249B grade steel, equivalent to Russian AB2 grade steel that went
into manufacturing of India’s first indigenously-built aircraft carrier.
Apart from supplying steels for building warships,
ASP regularly supplies armour grade steels like Spade, Jackal to
defence sector through RSP or BSL-RSP route, besides supplying special
steels for arms & ammunition to ordnance factories. ASP’s average
annual sale to defence sector exceeds 12,000 tonnes.
Kolkata, April 4 – Alloy Steels Plant
(ASP) of SAIL said on Thursday that it produced for the first time in
the country a special grade steel (DMR-292A), meant for use in
submarines, for the Indian Navy. The high-strength and low temperature
item was manufactured according to the specifications developed by
Defence Metallurgical Research Laboratory (Hyderabad ) of Defence
Research & Development Organisation. The steel will be processed to
plates through Rourkela Steel Plant (RSP) directly or via Bokaro Steel
Plant before supply to DMRL for further testing, a SAIL source said. The
steel would be then ready for certification. The commercial production
of this grade at ASP would add to SAIL’s capability in the field of
special steel. ASP, currently enjoys a stable partnership with defence
establishments of the nation. Last year, it supplied another special
(DMR-249B) grade steel, equivalent to Russian AB2 grade steel that went
into manufacturing of India’s first indigenously-built aircraft carrier.
Apart from supplying steels for building warships, ASP supplies armour
grade steels such as Spade amd Jackal to defence department through RSP
or BSL-RSP route. It also provides special steels for arms and
ammunition to Ordnance Factories. ASP’s average annual sale to Defence
sector exceeds 12,000 tonnes now. ASP primarily supplies steel items to
the institutional sectors such defence, the Railways and their sister
units.
