  1. About Mittal Group • Mittal Group is an established manufacturer of Stainless steel, Alloy Steel and Mild Steel long products • The group manufacturing activities cover following process of steel industry: • Steel Making: Production of liquid steel in variety of grades in Stainless/ Alloy/ Carbon Steel. • Rolling : Rolling of billets into wire rods and bars in variety of grades in Stainless/ Alloy/ Carbon Steel. • Mittal Group operates three units strategically located in central part of India near Indore: • Mittal Corp Limited: • Unit I (Steel Melt Shop & Flat Rolling mill) Capacity: 120,000 TPA • Unit II (Bar & Wire Rod Mill) Capacity: 150,000 TPA • MCL Global Steel Private Limited-Under final stage of commissioning • Steel Melt Shop Capacity – 208,000 TPA

  2. Mittal Corp Limited (MCL) • MCL’s product range includes Billets, Flats, Wire Rods, rounds, QTR/QTB reinforcement bars, Stainless Steel Reinforcement Bars. • MCL is first in India to launch Stainless Steel Reinforcement Bars most suitable for RCC structures in marine environment, aggressive industrial environment & for monumental structures built for life-time. Stainless Steel Reinforcement Bars increases life of RCC structure more than 5 times as compared RCC structure with carbon steel structure.

  3. MCL's Certification ISO 9001:2008 ISO 14001:2004 For Quality Management For Environmental Management MCL’s facilities are certified as above

  4. MCL Steel Melt Shop : Unit I • Melting and refining facilities to produce Billets & Blooms in AISI 200 , 300 and 400 series of Stainless Steel Grades through IF – AOD - LRF – CC route. • Equipped with Rolling Mill to produce Flats. • Product profile: Stainless Steel/Mild Steel Billets Stainless Steel/Mild Steel Flats

  5. MCL’s Bar & Wire Rod Mill: Unit II • Bar & Wire Rod Mill is a newly installed flexible rolling mill of capacity 150,000 tonne per annum • Spread over 22 Acres, this plant is a forward integration to Steel Melt Shop - Unit-I for manufacturing Wire Rods, Rounds, QTR/QTB Reinforcement bars (TMT Bar) & Stainless Steel Reinforcement Rebar's as per international standards • Plant, machinery and equipments have been procured from Danieli Morgardshammar, Italy acknowledged global leader in manufacturing of rolling mill and steel plant equipment

  6. Key Features: New State of the Art Rolling Mill • The key features of the Plant, Machinery & Equipment are: • PLC controlled Reheating furnace with facility to run on furnace oil as well as RLNG, with moving hearth for uniform heating and low scale formation, with input size of 160 x 160 x 6000 mm billet, taken from Danieli Centro Combustion. • De - Scalar before roughing stand to remove scale formed during reheating. • Intermediate rolling on Horizontal - Vertical roll configuration for better control during rolling due to no twist arrangement.

  7. Key Features..Contd. • P800 Series Horizontal Vertical type Ten stand wire rod block, from Morgardshammar with post rolling arrangement of Water Quenching, Forced Cooling and Retarded Cooling to achieve required grain size / structure and mechanical properties for different grades. • Level II Automation to ensure dimensional tolerances better than International designated Standards in accordance with requirement of discerning customers. • New Garret Line is under installation to manufacture Wire Rods up t o 40mm.

  9. Corrosion Phenomenon • Reasons for corrosion in RCC Structure: • Moisture ingression • Exposure of structure to marine environment • Exposure of structure to aggressive industrial environment. • Cracks due to Mechanical Loading. • Presence of stray currents. • High water-cement ratio in RCC structures. • Low concrete tensile strength. • Electrical Contact with dissimilar metals. • Corrosion due to difference in environments.

  10. Photographs of Corrosion in RCC Structures

  11. Photographs of Corrosion in RCC Structures

  12. Photographs of Corrosion in RCC Structures

  13. Photographs of Corrosion in RCC Structures

  14. Prevention of Corrosion • Epoxy coating of steel re-bars. • Galvanize/Galalume coating of steel re-bars. • Addition of Corrosion inhibitors in RCC. • Cathode Protection. • Increasing concrete cover. • Chloride Extraction – By chemical spraying. • Concrete Coatings by Sealers. All the above procedures enhances the life of the structure in varying degree from 10-15 years only. Cost of maintenance is also high & during the designated life time of the structure. Also the maintenance cost can be more than the initial cost of structure in some cases

  15. Make In India- For the 1st time in complete range of sizes The Cost Effective solution to corrosion of reinforcement material Stainless Steel Re-Bars We recommend

  16. Studies on Stainless Steel Re-Bars Stainless Steel Rebar besides being cost – effective as proved by independent studies carried out on SS rebars. Some of the studies done are listed below: • “Improving Tomorrow’s Infrastructure: Extending the Life of Concrete Structures with Solid Stainless Steel Reinforcing Bar” - by Bergmann and Schnell. - Improvements in the life of the reinforcing can translate directly into extended life of the structure. • “Corrosion Resistance of Alternative Reinforcing Bars: An Accelerated Test”  by Wiss, Janney Elstner Associates - SS 316 and 2205 stainless bars exhibited phenomenal low corrosion rates, approximately 0.1 percent of conventional steel. • “A Pilot Experimental Study on the Low Cycle Fatigue Behavior of Stainless Steel Rebars for Earthquake Engineering Applications” by Yihui Zhou, Yu-Chen Ou, George C. Lee and Jerome S. O’Connor, University at Buffalo  –  In general, the three types of stainless steel (Enduramet 32, 2205 duplex and 316LN), are better than A706 G60.

  17. Studies…Contd. • “Effects of Galvanic Coupling between Carbon Steel and Stainless Steel Reinforcement in Concrete” by Bertolini, Gastaldi, Pedeferri and Pedeferri • “Galvanic Coupling between Carbon Steel and Stainless Steel Reinforcements” by Qian, The judicious use of stainless steel with carbon steel in the high-corrosion-risk areas of a concrete structure can be a cost-effective option for reducing corrosion and greatly extending the service life of concrete structure. • D.B. McDonald, D.W. Pfeifer, Y.P. Virmani, Corrosion-resistant reinforcing bars Findings of a 5-year FHWA Study. Int. Conf. Corrosion and Rehabilitation of Reinforced Concrete Structures.FHW, Orlando 7–11 December 1998. • B. Elsener, L. Bertolini, R.B Polder, P. Pedeferri, Corrosion Of Steel In Concrete Prevention, Diagnosis, Repair, John Wiley and Sons Ltd., Weinheim, 2004. • “Guide for use of Stainless Steel Reinforcement in Concrete Structures” Nordic Innovation Centre Project 2006

  18. Application of Stainless Steel Re-Bars • River crossings & Highway bridges. • Highway underpass & Tunnels • Sea Walls & quays • Coastal structures • Structures where De-caking of ice by salt spray is done • Airport bridges & taxiways • Piers, docks and moorings • Water and sewage treatment plants • Concrete structures in refineries, chemical processing

  19. Application of Stainless Steel Re-Bars..Contd. • Plants and power generating plants • Concrete structures subjected to very low temp (Ex. liquefied gas storage) • Restoration of heritage buildings • Monumental building build for life time • Strengthening of old bridges

  20. Benefits of Stainless Steel Re-Bars • Long Term Cost Advantage-Near Zero maintenance cost for designated life of the structure. • Low Life Cycle Cost-Almost Corrosion Free • Earthquake Resistant Properties • High Mechanical Strength, Low Thermal Expansion, Good Weld ability, High Energy Absorption, Good Fatigue Resistance • Stability at Low & High Temperatures- SS-Rebar can be used in frost & cold environments which causes cracking & splitting from the steel beneath as well as has superior resistance to heat at elevated temperature “BUILD IT & FORGET IT”
