Carbon Steel / Flux Cored / Gas Shielded

Resources

Features

  • Intended for welding of carbon steels such as ASTM A36, A285, A515-Gr 70, and A516-Gr 70
  • Can be used with both 100% CO₂ and blends of 75-90% Ar/balance CO₂.
  • Well suited for general fabrication of carbon steels abd structural steel welding
  • Tensile strength is slightly lower than most other carbon steel all-position products, providing less overmathcing of strength on carbon steel plate materials.
