INTERNATIONAL CLASSIFICATIONS

AWS/ASME A 5.15 EST

ISO 1071: E Fe

DIN 8573: E Fe-1

FEATURES & APPLICATIONS

For non-machinable welds on machine bases, furnace grates, exhaust manifolds, etc.

  • Nickel free cast iron problem solver, seals in porosity generating contaminants prior to finish welding with nickels.
  • Easily clads heat oxidized and oil impregnated castings.
  • Perfect color match to cast iron.
  • Non-conductive flux coating.
