Select 115-K4

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • The basic slag system provides better mechanical properties and lower diffusible hydrogen levels in the weld deposit than T-1 (rutile) slag systems.
  • Arc transfer is globular and more spatter is produced than with T-1 slag systems.
  • Select 115-K4 is an improved T-5 electrode with slag removal and bead geometry similar to that of E10018 electrodes
  • Ideal for welding T-1, HY-100, ASTM A514, and other HSLA steels of similar strength.
