Socony-Mobil BuildingThe 42-storey Socony-Mobil Building wasbuilt in 1956. It was the world’s largestmetal-clad building at that time. Itsexterior uses 40,500 m2 of nickel-containing S30200 stainless steel. Theexterior was cleaned for the first time in1994 (nearly 40 years after installation).

A simple scrubbing with a mild non-acidic,non-abrasive detergent removed the dirtand grime of 40 years of exposure to New

Sustainable development:Stainless steel is the most recycledmaterial in the world – even more thanglass and paper. It is recycled almost100%. On an average, 60% of the chargegoing into the furnace for makingstainless steel is recycled material. Itdoes not need painting. During its servicelife, it does not deteriorate or give rise tocorrosion products.

Optical Flatness:The core of LDPE with stainless steelouter sheets makes the panelexceptionally stiff. This results in aproduct with very superior optical flatnesswhich the architects greatly value. Suchoptical flatness if not easily attained incase of plain metallic sheets unless oneuses substantially higher thicknesseslike 3 or 4 mm in order to avoidappearance of waviness (called ‘OilCanning’).

Impact and load resistance:Apart from high stiffness, this three - layercomposite panel greatly improves impact(dent) resistance. This makes SCP muchbetter suited for areas of heavy pedestrianmovements where accidents andvandalism are possible, compared tosofter materials like aluminium. Thisthree-layer composite also provides thepanel excellent torsion and bendingstrength for the exterior walls which tendto sway under wind loading.

Thermal Insulation:LDPE core has very good thermalinsulation properties. With stainlesssteel itself not being a good conductor ofheat, their combination in SCP gives a

product which is an ideal material forinsulating the interiors from externalheat.This directly results is huge savingson utility bills for air-conditioning.

Weathering ability:Stainless steel is unaffected by long-termexposure to ultraviolet rays and significantchanges in ambient temperature all yeararound. It can withstand extreme weatherconditions and not corrode, deteriorateor lose its sheen.

Fire resistance:Composite panels with a fire-resistantcore, in combination with the highresistance of stainless steel to hightemperature deformation, have excellentfire resistance characteristics. Even atflame temperature, stainless steel willretain half of its room temperaturestrength. The absence of paints avoidsnoxious fume generation.

Sound Insulation:Compared to plain metallic sheets, tiles,marble, granite and wood, SCP havemuch higher sound dampening abilityand greatly help in cutting down thetransmission of street level noises.

Easy, cost-effective installation:The coefficient of thermal expansion ofstainless steel is only three-fourths thatof aluminium. Because of the high levelof rigidity of SCP, there is no requirementof additional reinforcement or thermal/noise insulation. Installation becomes alot easier and cost-effective.

The trapezoidal cladding used on the endwalls of the building is made from1.5 mm S31600 stainless steel. It has aNo. 4 finish giving it the low reflectivity,high-quality appearance which is sopopular with architects.

The building is washed twice a year, andthe stainless steel trapezoidal claddinglook as good as new. In comparison, theold aluminium curtain walling has beencompletely replaced with new. (Thismatter is extracted from a report in‘Nickel’ Magazine, 42 years after thebuilding was constructed.)

Forever YoungThe Thyssenhaus was one of the firststeel-framed, curtain–walled high risebuildings to be constructed in Europe.Designed by Dr. Ing. Hentrich in 1956with stainless steel cladding on twosides and aluminium curtain-walling onthe others, it quickly became the landmark building in Dusseldorf. Even today,it looks just the same as it did in 1956.

‘Singara Chennai’ in Tamil means‘Beautiful Chennai’. ‘Singara Chennai’ isthe project of Chennai Corporation toenhance the image of the city. As a partof this exercise, Chennai Corporationhas replaced 10 existing traffic umbrellasin the city with modern and state-of-the-art stainless steel Traffic Umbrellas ona trial basis.

As you can observe from the photo, thenew stainless steel traffic umbrella givesa contemporary look and feel to the trafficintersection. This make-over is not justfor the looks. They add invaluablefacilities and comfort to trafficconstables. These include a cushioned360o rotating seating, concealed lightingand fan (which you need all year aroundin Chennai), a first aid box, a trafficcontrol console within comfortablereach, a utility cabinet for the constable,provision for displaying social/civicmessages, a public address system andmost important, a wind / dust / rain guardmade of clear acrylic sheets to protectconstables from the harsh environmentof Chennai.

Chennai Corporation seems to havemissed out on airconditioning and toiletfacility?Everything else has been takencare of for the constables to do their jobin relative comfort.

The old Traffic Umbrellas were justumbrellas stationed at intersections forpolicemen to regulate traffic. Trafficpolicemen were fully exposed to heat anddust, and rain during the monsoons. Noplace to sit, plus total exposure to noxiousexhausts of vehicles.

In order to minimize the buildup ofradioactive contaminants in the primarynuclear reactor-to-steam generation unit ofnuclear power plants, very high purity wateris circulated. Specifications limit the totaldissolved solids (TDS) in the water to onepart per million (ppm). The limit of 1 ppmis an order of magnitude less than in themost pristine fresh waters.

This limit of 1 ppm is so far below thesolubility of most common materials inwater that a new phrase, hungry water,was coined to describe the high level ofcorrosiveness of 1 ppm TDS high puritywater. This very hungry water dissolvesmost radioactive species, preventing theiraccumulation in the system.

To give an example, we make iron & steelout of iron ore, which is essentially madeof oxides of iron. By extracting oxygenfrom the ore, we get iron and steel. If steelis left in the atmosphere, it is desperate toreturn to its original form, that is, to goback to its natural state again, i.e.,become oxides of iron. We call thisphenomenon rusting. We see thishappening all the time with unprotectediron and steel surfaces in the presence of

leaving a frosty or etched appearance. Fewengineering materials, other than stainlesssteel, can contain 1ppm TDS water withoutlosing some species to the water andincreasing TDS. Clean stainless steel canhold 1 ppm water without measurableincrease in TDS over long periods of time.This ability to keep high purity water justthat – high purity – is a major reasonthat stainless steel has become thestandard material of construction fornuclear power plants.

The ability of stainless steel to hold highpurity water is due to the highly protective,tenacious and self-replenishing nature ofthe passive film that forms on stainlesssteel. The film is so thin (only a fewAngstroms (10-10 meters thick)) as to betransparent and, so readily formed, thatwhen scratched it reforms instantly in airor water, as long as there is any oxygenpresent.

Such very high purity water is also neededfor pharmaceutical plants, biologicallaboratories, hospitals and food processindustries. These industries use stainlesssteels extensively to ensure very high levelsof hygiene in their products and services.

“Hungry Water” necessitates use of stainless steel in Nuclear Power Plants

moisture. What we are seeing here is thehunger of purified iron for its original stateof being combined with oxygen. Similarly,the 1 ppm TDS highly purified water hasan extreme ”hunger” for impurities suchas minerals which exist in natural water.That is why most materials cannotwithstand the corrosiveness of “hungrywater”.

This water is such a good solvent for nearlyall materials that at this artificially depletedlevel, it will leach silica out of glass,

The Stonecutters Bridge is located acrossthe Rambler Creek at the entrance to oneof the busiest ports in the world, the KwaiChung container port in Hong Kong. Thisport has played and continues to play akey role in the economic and commercialsuccess of Hong Kong and China.Between the years 1987 and 2004, it wasrated 15 times as the busiest containerport in the world. In 2005-2007, it wasranked third busiest in the world behindShanghai and Singapore.

A bridge across the Rambler channel wasdesperately needed to reduce travel timebetween the new Hong Kong airport andKowloon—the commercial hub of HongKong. It was also needed for speeding themovement of containers to and from thePort.

The need for keeping the sea lanes clearfor passage of even the biggest ships, andat the same time providing quick roadtransportation from the airport to Kowloon,

posed a simple but gigantic question. Ifthe bridge were ever to be repaired, itwould certainly hold up or restrict thesea lanes. It would also congest cityroads. Such an eventuality couldseverely hurt Hong Kong and China’seconomy.

The solution was to build a long lastingbridge which would not need anymaintenance at all for 120 years; a ZEROmaintenance bridge.

This was achieved by using stainless steel304 grade reinforcement bars in theconcrete piers and the main towers’ splash

zones. A total of 2,882 tonnes of rebar indiameters up to 50mm was used.

Hong Kong is prone to very strongtyphoon winds. Considering this, the twomain towers which rise 290m into thesky, had to be designed in concrete upto level 175m and a compositeconstruction consisting of inner concretecore with a stainless steel skin for thetop 120m. Stainless steel grade S32205was chosen to satisfy the rigorousstructural and surface finishrequirements. About 2,000 tonnes hotrolled plates of S32205 were used for thispurpose. It could be clearly seen that useof conventional steel structure above level+175m would have been too lively andlead to unacceptable vibrations of thestay cables.

Its deck will soar 75 meters above theentrance to Hong Kong’s Kwai Chungcontainer port, allowing large ocean linersto travel under it. When it is completed thisyear, the 1,600-meter-long StonecuttersBridge with a span of 1,018 meters andsoaring 290 meters into the sky will be akey component in China’s global tradeactivity. The combination of duplex towersand stainless steel reinforcing bar shouldresult in a bridge that will endure.

According to a recent report in the Timesof India (April 12, 2009), India is planningto set up several massive nuclear powerparks. These will be located in Jaitapur inMaharashtra, Haripur in West Bengal,Patisonapur in Orissa, Mithirvirdi inGujarat and Kowadi in Andhra Pradesh.Six to eight reactors of 1,000-1,650 MWwill be installed at each nuclear park.Negotiations are in progress with fourglobal suppliers – GE-Hitachi, Toshiba-Westinghouse, Areva of France andAtomstroyeksport of Russia.

According to the analyst Mr. SwaminathanS. Ankalesaria Aiyar, “all foreign nuclearsuppliers will transfer technology andindigenize production in India. Mr. Aiyarexpects this because when South Koreaand China placed major orders for nuclearpower plants, they mandated transfer oftechnology and localization of equipmentthey manufacture”.

MNCs involved are also keen to set upjoint ventures in India because of the lowcost of production and availability oftechnical manpower. In addition, Westernmanufacturers find the construction costsof nuclear power plants spiraling, makingit less attractive to build new nuclearplants. One way to sustain resurgence ofthe nuclear power industry is to constructplants and establish nuclear partsproduction in low cost countries.

DISCLAIMER

In the wake of sustainability concernsaround the world, nuclear power, untilrecently labeled “expensive and unsafe”,is suddenly seen as being essential toproduce emission-free electricity.Worldwide, the demand for nuclear powerequipment is expected to quadruple in thenext decade. The best way to meet thisdemand is to create much of theinfrastructure in countries such as Indiaand China, which have technical skills, lowcosts and large local demand.

Only one plant in France and one in Japancan make the giant forgings needed forlarge nuclear power plants. Bharat Forgeof India has recently signed a pact withAreva of France to manufacture nuclear

equipment – including giant forgings.Larsen & Toubro has signed a similarnuclear equipment deal with Mitsubishi.

Such an emerging scenario could makeIndia an exporter of nuclear equipmentapart from meeting its own growing needs.According to market analysts, 750 tonnesof stainless steel long products,essentially in the form seamless tubes,and 250 tonnes of flat products are neededfor every 500 MWe of nuclear powerproduced. Apparently stainless steelgrades AISI 304L, 316L and 347 willdominate. Nickel alloys such as 600 and690 are also used, depending on theseverity of service environment.
