SelectAlloy 2209-AP

Stainless Steel / Flux Cored / Gas Shielded

Resources

Features

  • This alloy type is characterized by high tensile strength, resistance to stress corrosion cracking, and improved resistance to pitting compared to traditional 300 series type stainless steels.
  • Designed for welding in all positions where well washed beads can be achieved with minimal weaving.
  • Smooth arc transfer produces minimal spatter with excellent slag release.
  • Applications include welding of duplex stainless steels which contain approximately 22 wt% Cr, such as UNS S31803 and S32205, that are commonly used in the chemical and fertilizer industries as well as off-shore pipelines and sour gas lines.
