What are Duplex Steel Round Bars?

Duplex steel round bars are made from a type of stainless steel that combines features of austenitic and ferritic stainless steel. These round bars exhibit excellent corrosion resistance, high strength, and weldability. The dual-phase microstructure provides enhanced toughness and resistance to stress corrosion cracking. Duplex steel round bars find applications in diverse industries, including chemical processing and construction, for components such as valves, pumps, and structural elements. Common grades include S31803 and SAF 2205 (UNS S32205), known for their reliability in corrosive and high-stress environments.

Properties of Duplex Stainless Steel Bar

Duplex Steel Round Bar properties
  • Corrosion Resistance
    Duplex steel round bars offer excellent corrosion resistance in aggressive environments containing chlorides, acids, and other corrosive substances. This resistance is attributed to the high chromium, molybdenum, and nitrogen content.
  • High Strength
    Duplex stainless steels, including round bars, possess high tensile and yield strength. This strength makes them suitable for applications requiring structural integrity and load-bearing capacity.
  • Good Weldability
    Duplex steel round bars generally have good weldability when proper welding procedures are followed. This allows for the creation of strong and durable welded joints, making them versatile in fabrication processes.
  • Enhanced Toughness
    The dual-phase microstructure (austenitic and ferritic phases) contributes to enhanced toughness, resisting impact and vibration. This property is crucial in applications where structural robustness is essential.
