Select ER2209

Stainless Steel / Solid / Flux Shielded

Resources

Features

  • This duplex stainless steel is characterized by high tensile strength, resistance to stress corrosion cracking, and improved resistance to pitting compared to traditional 300 series type stainless steels.
  • Applications for this alloy type include welding of duplex stainless steels that contain approximately 22 wt% Cr, such as UNS S31803 and S32205.
  • Commonly used in the chemical and fertilizer industries as well as off-shore pipelines and sour gas lines.
