Research and Development Development of value added products Process improvement Cost reduction Quality up gradation Development of new process route

Product Development - Austenitic Stainless Steels- 300 Series  Heat resistant stainless steels- 309S, Monophase Austenitics: 310S, X8 Cr Ni Nb  Corrosion Resistant S.S.- 316, 316L, 317,317L  Stabilized Stainless Steels 321, 347  High Purity Stainless Steel for Nuclear Applications

PRODUCT DEVELOPMENT 304 L (NAG) Very low inclusion level : (A+B+C+D<4) IGC Practice C : < 5 mpy

PRODUCT DEVELOPMENT Indian Railways & Delhi Metro 301, 301 L – different tempers High strength and good corrosion résistance 409 M Used for making railway wagons, superior to CORTEN steel

PRODUCT DEVELOPMENT Ferritic Stainless Steels Automotive Stainless Steel 409L, 436L Exhaust muffler of automobile The composition and the heat treatment been tailored to achieve excellent formability Supplied for the manufacturing of car like Santro and Palio

PRODUCT DEVELOPMENT Ferritic Stainless Steels SS-430 coin blanks Mint – Govt. of India French Mint Commissioning of blanking, rimming, blank annealing and polishing line Designing chemical composition to achieve hardness < 150 VPN Finish : Bright annealed

Martensitic Stainless Steels / 410S/ 410DB Razor Blade Steel

PRODUCT DEVELOPMENT JBS Y – Razor Blade Steel 0.10 mm x 22.2 mm strips Fine primary carbide Secondary Carbide distribution : 50 – 60/100 micron 2

Duplex Stainless Steels The only producer in India Having dual microstructure of ferrite and austenite. 2205: 22Cr-5Ni-3Mo Extensive application in sour gas piping, offshore drilling rigs, marine structures. 2304: 23Cr, 4Ni For Paper & Pulp Industry

Austenitic Cr-Mn Stainless Steels Ni Free J 15Cr: 15Cr-10Mn-1.5Cu J 4: 15.5 Cr. 9Mn-1Ni-1.5Cu J 204Cu: 16Cr-1.5Ni-2Cu AISI 201: 16Cr-4Ni JSL AUS (J1): 16Cr-4Ni-1.5Cu AISI 202: 17Cr-4Ni J 204: 18Cr-4.5 Ni
