NiFe-CI
Description
Ni-Fe flux cored wire for cast iron
This nickel alloyed tubular wire has 36 % Ni because at this Ni content an iron alloy has
the lowest possible thermal expansion rate. Steel with this
composition does not expand up to 200°C. This physical property
makes the alloy suitable for the welding of cast iron parts and all
applications where tension of shrinkage should be avoided. It is
machinable. Used for joining and repairing nearly all types of cast
iron. To limit internal stress of the base metal, hammering
of the beads is recommended after each pass.
