  1. RESEARCH & DEVELOPMENTDEPARTMENT JINDAL STAINLESS LIMITED

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

  3. Product Development - Austenitic Stainless Steels- 300 Series • Heat resistant stainless steels- 309S, 30815 Monophase Austenitics: 310S, X8 Cr Ni Nb 16 13 • Corrosion Resistant S.S.- 316, 316L, 317,317L • Stabilized Stainless Steels 321, 347 • High Purity Stainless Steel for Nuclear Applications

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

  5. 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

  6. 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

  7. 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

  8. Martensitic Stainless Steels • 403 • 405 • 410 / 410S/ 410DB • 415 • 420 • Razor Blade Steel

  9. PRODUCT DEVELOPMENT JBS Y – Razor Blade Steel • 0.10 mm x 22.2 mm strips • Fine primary carbide • Secondary Carbide distribution : 50 –60/100 micron2

  10. 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

  11. 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

  12. Jindal stainless has now developed a grade J204 which matches corrosion resistance of 304 in a variety of media Suitable for many industrial applications: 500X 500X 204 (weld zone) 304 (weld zone)
