Duplex steel sheets/plates are flat, thin pieces of material made from duplex stainless steel. Duplex stainless steel is a type of stainless steel that contains a two-phase microstructure consisting of roughly equal portions of austenite and ferrite phases. This dual-phase structure provides a combination of excellent corrosion resistance and high strength, making duplex steel sheets/plates highly suitable for a wide range of applications in various industries.

Advantages of Duplex Steel Sheet/Plates

Duplex Steel Sheet / Plate
  1. Excellent Corrosion Resistance: Duplex stainless steel offers superior corrosion resistance compared to conventional austenitic stainless steels, particularly in chloride-rich environments like seawater and chemical processing.

  2. High Strength: Duplex steel sheets/plates have higher strength levels than austenitic stainless steels, allowing for thinner material thicknesses and reduced weight in structural applications while maintaining structural integrity.

  3. Cost-Effectiveness: While duplex stainless steel may have a higher initial cost compared to austenitic stainless steels, its superior corrosion resistance and mechanical properties often result in long-term cost savings through reduced maintenance, repair, and replacement expenses.

  4. Versatility: Duplex steel sheets/plates are versatile and can be used in a wide range of applications across various industries, including oil and gas, chemical processing, marine engineering, pulp and paper, and architectural applications.

  5. Weldability: Duplex steel sheets/plates are readily weldable using common welding techniques, allowing for ease of fabrication and assembly into complex structures without compromising corrosion resistance or mechanical properties.
