SelectAlloy 2209-C

Stainless Steel / Metal Cored / Gas Shielded


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.
  • Metal cored benefits include the ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
  • 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.
