INTERNATIONAL CLASSIFICATIONS

AWS/ASME A 5.15 E NiFe-CI-A
DIN 8573: E NiFe-1 BG23

ISO 1071: ENiFE
NFA 81-342: E Ni BG 23

FEATURES & APPLICATIONS

Universal electrode for joining a wide variety of ductile, nodular and malleable cast irons. Ideally suited for the repair of meehanite dies.

Non-overheating, hard driving, Ferro-Nickel electrode for penetrating dirty-rusty contaminated cast irons.

  • Excellent for joining cast iron to steel.
  • Extremely strong arc drive penetrates surface contaminants.
  • Special slag composition can be welded over without creating porosity.
  • Extra nickel content insures crack resistant machinable welds.
  • Also available in TIG form as product code 6044.
