FEATURES & APPLICATIONS

Wherever maximum ductility is required when joining dissimilar steels to themselves or to stainless steels.

  • Extra strong and tough stainless steel electrode for joining steels to stainless steels.
  • Highly recommended for joining hard to weld steels.
  • Moisture resistant coating provides sound porosity free deposits.
  • Slag is self-removing.
  • Also available in TIG form as product code 6090.
