Tata to unveil new lightweight armour steel

[Gessler]

Tata Steel's Lightweight Armour Steel Can Take A Punch

Tata Steel has received orders for more than 200 samples of its perforated
armour steel, which has been exported to a number of countries worldwide
including Germany, France, the USA and India. This revolutionary armour steel,
formerly known as Super Bainite, has also undergone a number of design
improvements and has taken on a new brand name, PAVISE SBS 600P.

The company will be exhibiting its PAVISE product at next week's DSEI show,
the world-leading defence and security event, which runs from 10-13
September at the ExCel London exhibition centre.

PAVISE, which provides an efficient and cost-effective armouring solution for
military vehicles, as well as for defended infrastructure such as watch towers
or sangars, has now been tested up to STANAG Level 4 to create armour
capable of resisting both small arms and heavy machine gun fire with
armour-piercing projectiles.

The ballistic performance of PAVISE - the way it deals with the effect of
projectiles - is at least twice that of conventional rolled homogenous steel
armour. The perforated design of the steel creates a large number of edges
which disrupt the path of incoming projectiles, significantly reducing their
potency.

Dr Henrik Adam, Tata Steel's Chief Commercial Officer in Europe, said: "Tata
Steel has spent significant effort developing this unique product and we are
delighted with its performance. As a company we are well positioned to
support the market, both in the UK and the wider European markets, and
we look forward to receiving the feedback of all the companies currently
testing PAVISE."

A challenge Tata Steel has addressed and overcome since the product's
launch in 2011 is how to create the perforations in a cost-efficient way.
The former production route involved drilling round holes into hard armour
steel, which was difficult and expensive. By developing a process to
mechanically punch the metal before the steel is hardened, and by making
the holes smaller and narrower, Tata Steel has managed to reduce the cost
of the perforation process ten-fold. It is also now possible to bend the steel
into tight angles in the perforated condition, before hardening to ultra-high
levels of hardness.

One effect of the perforations is that the armour becomes almost transparent
at a distance of more than a few metres, due to the size and spacing of the
holes - a principle known as the Raleigh Criterion. This means the existing
camouflage of the vehicle is not compromised when the sections of PAVISE
are added.

Dr Paul Davies, product marketing manager for PAVISE at Tata Steel
said: "PAVISE offers increased design flexibility to achieve protection against
a wide range of threats, without compromising weight or modular performance.

"The number of samples that are already in the field being tested, and
the customers that have taken an interest in using them, demonstrate
the massive potential this product has for armoured-vehicle programmes."

Gus King, managing director of Permali Gloucester Ltd, a world leader in
the manufacture of composite materials for the defence industry, said:
"As part of a complete appliqué armour system we have found PAVISE
offers unique benefits in particular areas. Tata Steel can achieve impressive
lead times which match our composite materials and therefore allow fast
track design of new solutions."

Paul Davies will be available at DSEI on the Tata Steel stand, N9-498 in
the Land Zone, for any enquiries about the company's defence products,
including PAVISE SBS 600P.

It seems this is the result of largely European R&D. So would this technology be price competitive in the Indian market? Or would it even be marketed by be Indian arm of TATA in India?

Depends on the requirements put forward by our armed forces/para-military.

Of course this is how it works however with the TATA group being so large, would an Indian CAPF/ police/Armed forces requirement trigger this bein offered for the Indian market?


It's a bit of a stupid question I suppose.

I was just wondering if this product would be marketed by that TATA group in India even though it is pretty much a European product.

An earlier version of the steel was already sold here -

exported to a number of countries worldwide including Germany, France, the USA and India

Tata will first analyze the market situation here. It if finds out through it's sources that this type
of advanced steel has people looking for it in India, they will market it here. If not, they will keep
it to Europe/North America only.

However I think Indian military (not the paramilitary) will have access to it even if it's not available
on the public market here. As I said, it depends on the requirement.

Anyway, the money will come to Indian companies, regardless of where the product is sold.

marketed to India- yes.
Manufactured in India- that is ?

It is. It has originated from the Corus acquisition. There is no reason at all why it cannot be marketed in India. In any case, this kind of specialised steel was being imported. Now Tata may even find it economical enough to set up a production-line in India under the ambit of their group company Special Steels Ltd. In any case they now own the IPR to do so.

isn't some controversy, that they will not transfer this technology to TATA India unit even though they own IPR. They accepted this norm and acquired the firm. Don't know they signed the legal document or not.
How can production start in India!
