E2209-16 Duplex Stainless Steel Welding Electrode

E2209-16 is a rutile-coated duplex stainless steel welding electrode classified to AWS A5.4 / ASME SFA-5.4 E2209-16. It produces ferritic-austenitic weld metal with high strength and good resistance to pitting, intergranular and stress corrosion. It is primarily used for Duplex 2205, UNS S31803, UNS S32205 and SAF 2205 in oil and gas, offshore, chemical processing, piping and marine applications.

Designed for Duplex 2205

E2209-16 is specifically developed for 22% Cr duplex stainless steel. Its Cr-Ni-Mo-N weld metal provides a balance of strength and corrosion resistance while maintaining the ferritic-austenitic duplex structure.
Typical features include:
  • High pitting corrosion resistance
  • Good stress corrosion cracking resistance
  • High weld metal strength
  • PREN around 35–37
  • Service temperature up to 250°C

Base Materials & Applications

Typical base materials:
  • Duplex 2205
  • UNS S31803
  • UNS S32205
