SAF Steelcored 48 HD description: STEELCORED 48 HD is a seamless copper coated special rutile cored wire for gas-shielded metal arc welding of weathering steels such as Patinax or Cor-ten. The weld metal corrosion behaviour is adapted to these steel types. Excellent weldability. Very good slag removal, smooth weld bead surfaces without undercutting into the base metal. Very good mechanical property values and highly X-ray proof. Can be welded in all positions with one parameter setting. Preferably used under mixed gas. The use of CO2 is possible.
