Make in India: Navy’s new warships to be made from Indian steel

[cerberus]

State-run Steel Authority of India (SAIL) has received an order for supplying steel for seven frigates to be constructed for the Indian Navy. This is the first time that the Navy’s new warships will be built using Indian steel. Earlier, warship-grade steel was imported from Russia.

“In all, 24,000 tonnes of steel would be supplied,” a spokesperson from SAIL said. Besides Bhilai Steel Plant (BSP), the other two SAIL entities including Rourkela Steel Plant (RSP) and Bokaro Steel Plant would be supplying the special warship-grade steel for the order. The share of BSP would be more.

Garden Reach Shipbuilders and Engineers Ltd (GRSE) in Kolkata would be building three advanced stealth frigates under the Navy’s Project 17A, while the rest will be built by Mazagon Dock Shipbuilders Ltd.
The order is in line of Make-in-India initiative. “The initiatives including indigenous manufacture of seven new frigates for Indian Navy for which SAIL is to supply steel translates into continued demand as well as fresh orders for our products,” a SAIL spokesperson said.

Earlier, SAIL had supplied DMR 249A grade plates that are specially toughened warship grade plates. It was used for constructing the hull of INS Vikrant, the aircraft carrier of Indian Navy that was commissioned in August 2013.

SAIL has thus successfully developed DMR 249A steel plates, thereby making the steel indigenously available for manufacture of Air Defence Ships and Corvettes by Indian Navy. The company had supplied more than 26,000 Tonnes of DMR 249A steel plates in the last 9 years.

So it begins, P17A. @Abingdonboy

Kamorta was the first to use this steel, btw.

is it official design?

is it official design?

It's the only design we have seen of it. Cant say it's official, but I would bet on it.

i hope it is bcos this looks awesome.certainly more stealthy then shivalik.

Here's the steel used.

Made by DRDO, produced by SAIL.

Looking good. A similar development from last year that featured in The Hindu:

Salem Steel Ltd. (SSL) has successfully developed and processed aerospace grade stainless steel slabs for ISRO on a trial basis.

“For the first time, we have indigenously developed and processed the aerospace grade stainless steel in Salem. The steel slabs were provided by ISRO. The end result was development of import-substitute exotic Russian grade (ICSS-1218) slabs that are used in the construction of the rocket launch vehicles. It will be shipped to ISRO’s Liquid Propulsion System Centre (LPSC) soon,” said a Salem Steel official.

Taking the help of ISRO scientists, a SAIL team processed electro-slag re-melted (ESR) and forged slabs. The final product conforms to ICSS-1218 that is equivalent to SS 321 grade stainless steel slabs.

“We have been regularly processing stainless steelfor various satellite launch vehicles, including the Polar Satellite Launch Vehicles that carried the Chandrayaan and Mangalyaan missions into the space,” he said.

Another official said that the culmination of the three-month trial processing of 321 grade stainless steel laid the foundation for a sustained collaborative ‘Make in India’ initiative between SAIL and ISRO for developing and processing other aerospace grades for the space launch vehicle components.

Expect the design of warship on the lines of Horizon class destroyers, why? Hint. See who is helping us out.....

Another,

As you see, it's basically the same.
