DETAILS

ULTRACORE® stainless flux-cored wires deliver consistent mechanical properties, superior arc performance, easy slag removal

Features

  • Precision layer wound spool delivers steady spool payoff and more consistent feeding
  • Smooth arc action with minimal spatter reduces post-weld cleaning
  •  Polished weld bead appearance reduces post-weld brushing

Typical Applications

  • Dissimilar joints – stainless types 410, 304L, 321, and 316L to mild and low alloy steels
  • Buffer layers and clad steels – overlays on CMn, mild steel or low alloy steels
  • Pressure Vessels

Welding Positions

  • Flat/Horizontal

Shielding Gas

  • 75% Ar/25% CO2
