Duplex stainless steel is a type of stainless steel that has a two-phase microstructure consisting of both austenitic and ferritic stainless steel. It is known for its excellent corrosion resistance and high strength. Duplex steel is used in various industries, such as oil and gas, chemical processing, and marine engineering. Here is a summary of the types of duplex steel and their applications:

  • Wire Rod: Used in welding and manufacturing of wire mesh, filters and springs.
  • Rolled Round Bars: Used in the manufacturing of shafts, fasteners and flanges.
  • Square and Hex Bars: Used in the manufacturing of valves, fittings and fasteners.
  • Bright Bars & Forged Bars: Used in the manufacturing of pumps, valves and other fluid-handling equipment.
  • Forged Gears: Used in the manufacturing of gearboxes for various applications.
  • Blocks, Die Blocks, Forging Ingots: Used in the manufacturing of large and complex components.
  • Flats, Sheets, Coils: Used in various applications such as structural components, cladding and tanks.
  • Angles: Used in the manufacturing of structural components and supports.
  • Plates: Used in the manufacturing of tanks, pressure vessels and heat exchangers.
  • Pipes: Used in various applications such as oil and gas pipelines, chemical processing and marine engineering.
