ISSDA is very pleased to inform itsreaders that the Indian Standard IS 15997: 2012 “Low Nickel Austenitic stainlesssteel sheet and strip for utensils andkitchen appliances – Specification” hasbeen released by Bureau of IndianStandards.

This Indian Standard was adopted by theBureau of Indian Standard, after the draftfinalized by the Alloy Steels and Steelssectional committee was approved byMetallurgical Engineering DivisionCouncil.

In India, utensils and kitchen appliancesare manufactured in large quantities byusing low nickel austenitic stainlesssteel. Keeping the interest of theconsumers in view, a need was felt toformulate an Indian Standard to facilitatemanufacture of low nickel austeniticstainless steel sheets.

Although Low-Nickel stainless steel wasintroduced in the 1980’s, the formulationof a standard for the use of these gradesin utensils and kitchen appliances hastaken a lot of time, energy and money toestablish. ISSDA has been at theforefront, attending BIS committeemeetings, organizing a battery of testsrelated to mechanical, chemical,corrosion and ion leaching. The metal ionleaching tests and study for foodcompatibility on these grades were donefrom the reputed Central FoodTechnological Research Institute.

ISSDA is very thankful to all those whohave contributed over the years in makingand shaping of this standard. In particular,ISSDA sincerely thanks Mr. K RAnanthanarayanan, a stainless steelconsultant, based in Bangalore for hiscommitment and use of his extensivetechnical expertise in accomplishing thisIndian Standard. He has beeninstrumental in the preparation ofnumerous samples for mechanical,chemical, corrosion, leaching and othertests and personally monitoring them.He was formerly with SAIL, Salem SteelPlant in their Products & ApplicationsDepartment.

Stainless Steel Reinforcement Bars in Building and Construction

Stainless Steel at Actual Construction Site – Beams & Columns

India has a very long coast line and manyRCC structures alongside are badlyaffected by corrosion. This has becomea cause of great concern, sincefrequently they encounter high cost ofmaintenance, and sometimes, inevitableaccidents.

The reason for such quick deteriorationof reinforced concrete is primarilybecause of corrosion of the carbon steelreinforcing bars. Corrosion of carbonsteel rebar is enhanced by chlorides inthe concrete, which may come from theoriginal mix due to their presence in thesand, aggregate, water or it canpenetrate through the concrete mix whenthe external surfaces of the concrete areexposed to seawater, marineatmospheres or de-icing salts. Thecorrosion product, rust, occupies agreater volume than the original steel bar

and this creates a pressure which causescracking and subsequent spalling of thesurrounding concrete as shown in Fig 1.

Building construction in Mumbai hasbeen facing this problem for a long timeand we frequently hear tragic news of oldbuildings collapsing due to distress in

concrete on account of rebar corrosion.This has forced governing authorities,structural engineers, architects andbuilders to put a greater emphasis onusing construction material which canhelp in avoiding corrosion of structures.Stainless steel reinforcement bars exhibita much higher corrosion resistance thanordinary black, galvanised or epoxy-coated rebars. Stainless steel hasinherent property to resist corrosionsince it forms a passive layer of chromiumoxide on the surface which preventsrusting. This layer is self-passivating in

nature and re-forms immediately even ifthe surface is cut, scratched ormachined.

The suitability of stainless steelreinforcement bar in building andconstruction has started drawingattention of building contractors and

government authorities. M/s OrbitCorporation Ltd is one of the very firstbuilders in the country to use thestainless steel rebars in their premiumconstruction projects, at NapeanseaRoad, Mumbai. They have alreadycompleted two of their premium projectsusing stainless steel reinforcement bars,named Villa Orb & Orbit Arya (Fig 2.)

Orbit has ascribed following uniqueproperties of stainless steel rebar whichhas encouraged them to use it in theirbuilding construction.

Stainless Steel at Actual Construction Site – Slabs

• Due to its non corrosive nature, thelife of the building increases manifold.

• By its use, the maintenance cost ofthe building is vastly reduced andeffectively increased the life of thebuilding.

• The cost of interiors of the buildingsis also reduced by using the material andthe consequent maintenance inside thebuilding due to leakage in kitchen indoorplumbing, bathroom etc.

• Extra cost for different types oftreatments such as epoxy coating/ usageof rust resistant chemicals / galvanizingof bars, etc. which are used during normalconstruction is avoided.

Orbit Corporation has informed that“These stainless steel rebars aresupplied by the stainless steelmanufacturer M/s. Sunflag Iron & SteelCo. Ltd. based at Nagpur. They arepioneers in manufacturing different qualityof stainless steel products. By theconstant innovative efforts of topmanagement (especially Chairman Mr.Ravikiran Aggarwal, M.D. & CEO Mr.Pujit Aggarwal), consultant M/s.Mahimtura Consultants Pvt. Ltd. andtechnical team, we have achieved newheights of developing & using such S.S.bars in our projects and deliveredunsurpassed quality to our customers”

Orbit has announced that one of theirproject, Villa Orb, has won two awards“The Best Residential Property of theyear - 2010 award in the category ofbuilding less than 1 lac sq ft of area ratedby CNBC AWAAZ CRISIL - CREDAIReal Estate Awards & presented inDUBAI & “Premium Residential projectof the year 2009 rated byACCOMMODATION TIMES” for theprimary reason that it has used stainlesssteel rebar for reinforcement of concrete

In addition to this, Orbit is using S.S.couplers of same physical and chemicalcomposition to achieve stronger lapjoints and to avoid any galvanic corrosionbetween dissimilar metals. These qualitycouplers have been speciallymanufactured for them by M/s. G. TechSplicing. New Delhi

Orbit is coming up with more projectswhere they have decided to use stainlesssteel rebars. Orbit AryaFig2. Villa orb

is an ISO 9001:2008 certified companymanufacturing surface finishing chemicals since last35 years.

The company has developed a new method toimprove the corrosion resistance of stainless steels.General corrosion resistance of stainless steelcomes from the formation of a thin passive layer ofchromium oxide on its surface. This new method isused as the final surface treatment operation afterproduction of the component. The new processincreases the chrome/Iron ratio with the passive layerby extraction of Iron and Iron oxide thus enrichingthe passive layer with chromium oxide. Then acontrolled heat treatment is done to change thestructure and thickness of the passive layer. Thisapplication can be done on all type of finishes andalmost all commonly used grades of stainless steel.

This process can also be applied effectively in therestoration of corroded surface thereby furtherincreasing the service life of the stainless steel. Thistreatment can also be applied to remove scale anddiscoloration without using pre-treatment such aspickling or mechanical de-scaling.

This process is based on surface treatment with awater based solution of a specially developed organiccompounds, which are biodegradable and produceno harmful waste.

Progressive Surface Systems Pvt Ltd. offers a widerange of applications for these surface treatedstainless steels. They have been supplying surfacetreated stainless steel parts in applications suchas in Automotive, Architecture, Food processingmachines, Steel furnitures, Fasteners and Springs,Pharmaceutical and chemical processing plants,swimming pools etc.

Case Histories

Hand rails made of S S tube, material AISI 304,polished grain 240 Grit, placed along the Atlanticseashore stained and corroded heavily and had tobe cleaned every 4 - 6 weeks. After cleaning withPOLINOX Protect for more than 1 year no corrosionhas reappeared.

Rolls Royce body parts including bonnetmade of S.S. 304 with brushed surface arepassivated by POLINOX Protect. During aperiod of four years no corrosion either on topor on the rear side appeared despite exposureto deicing salts.

Today stainless steel is manufactured allover the world. India has become the thirdlargest market in the world. Minimizingmanufacturing cost by introduction of newtechnologies for processing stainlesssteels is furthering this growth.

AOD is an important process inmanufacturing of stainless steel. Thebasic principles of manufacture ofstainless steel is to melt the steel chargein an electric arc / Induction furnace, addthe required alloying elements, transferthe melt charge to a converter and blowoxygen to burn out the carbon present inthe bath. Carbon is oxidized to carbonmonoxide. This is a reversible reactionand if carbon monoxide is not removedfrom the reaction zone, chromium presentis oxidized to chromium oxide. This canbe avoided by bubbling inert gases likeargon through the bath so that carbonmonoxide formed is immediately sweptaway thus leading to further oxidation ofcarbon and minimising the oxidation ofchromium. This process is called theargon-oxygen decarburisation process(AOD). Fig. 1 illustrates a typical AODconverter.

COST OF ARGON GAS

Though argon is the gas of choice in steeland stainless steel making, it is the mostexpensive gas used in the steel industry.Argon could be priced 8 to 15 times highercompared to oxygen. More than 70% ofstainless steel is produced by the AODprocess. About 10 Nm3 of argon isrequired per tonne of stainless steel.About 225 million Nm3 of Argon at a costof about Rs. 2.25 billion or US @ 45Million is needed for SS production peryear. Thus argon contributes significantlyto the cost of manufacture. Hence,recovery, purification and recycle of argonfrom the AOD process should beconsidered. Argon remains unchangedafter the process by its very inert naturethough it would be mixed with the productgases such as CO, CO2, O2 and N2 andalso will have considerable solidparticulate contamination. What however

is significant is that this gas has argonat about 15 to 40% and hence, this

should be a much better source of argonthan air which contains hardly 1%!

The present author has expertise inrecovering and reuse of argon gas fromsilicon single crystal growing furnaceby the Czochralski technique and has

developed a simple, cost effective andnon-cryogenic process for this purpose.This is in use for more than 15 years.The same process suitably modifiedcould be used for recovering argon fromthe AOD off-gases. A schematic of asimple argon recovery process proposedby the author is depicted in Fig. 2.

Recovery involves collecting the ventgas in a gas holder, compressing it toappropriate pressure and removingimpurities by suitable techniques.About 50 to 80% of argon could berecovered and reused. This leads tomany advantages including reduction ofcost of manufacture, carbon capturemaking the plant green, and availabilityof extra argon when capacity isexpanded. The process would be costeffective and easy to operate. Today,argon recovery is not being practised bystainless steel manufactures in India.However, the above process could beimplemented to reap good benefits.
