Industeel duplex

  1. 1. Widen your horizons with duplex stainless steels DuplexStainlessSteels-11-2011 Certifications Sizes Industeel Belgium 266 rue de Châtelet 6930 CHARLEROI BELGIUM Tel 32 71 44 16 99 Fax 32 71 44 17 14 Industeel France 56 rue Clemenceau BP 19 71201 LE CREUSOT CEDEX FRANCE Tel 33 3 85 80 59 93 Fax 33 3 85 80 54 11 www.industeel.info www.arcelormittal.com Duplex stainless steels are standardized throughout the world (ISO - ASTM - ASME - EN) for use in construction and pressure vessels. Industeel is ISO 9001 certified and approved by DNV - LLOYD’S - ASME - TÜV - NKK - BV etc… Industeel is NORSOK Rev 3 certified for UR 2205 (S31803), UR 2507 (S2750), UR 2507W (S32760). Tested and used in many different industrial chemicals : sulfuric, nitric, phosphoric, soda,... Generally more resistant than the corresponding austenitics to stress corrosion cracking in chloride containing media. Duplex are used for oil/refineries applications, in accordance with NACE MR0175 and API938C standards. Excellent resistance to abrasive particles in flowing corrosive slurries. Chemical application Duplex stainless steels can be used for building and construction in urban, industrial and marine environments. They have also been tested in soils with different resistivities, permeabilities and chloride contents.

  2. 2. From lean duplex to superduplex Know-how from a long experience Our production techniques, the in-service performances and our manufacturing properties knowledge are continuously improved. Industeel has developed duplex stainless plates for 70 years. Our experts from our Research Center are asked on material selection, forming conditions and metallurgy aspects. Duplex stainless steel plates, the material you need Strong Yield strength: 400 to 600Mpa (58/87Ksi) Ductile Elongation to rupture > 25 % Weldable By most of the common processes Corrosion resistant In various environments Affordable Weight/Cost savings Available In a wide range of plate sizes Safe From an experienced producer Environmentally friendly Lighter, no coating, 100 % recyclable In spite of their higher strength, duplex stainless steels can be sheared, bent, pressed, rolled into different shapes, hot or cold. Machinability varies with grade. Leaner grades are easy to machine. 53% 62% 67% 71% 75% Tests on as delivered and welded plates have demonstrated duplex good cold forming ability Cold deformation at end of test Usual service temperature : -40°C (-40°F) to 300°C (572°F).
