Description:
Elgaloy Cast-NiFe is designed to produce a higher, matching strength weld metal for joining malleable,
nodular and S.G. irons. It is also suitable for joining these to mild, low alloy and stainless steels.
Elgaloy Cast-NiFe is less sensitive to hot cracking sometimes caused by impurities in castings,
compared to pure nickel type electrodes. Thin sections can be welded cold, but thicker sections may
require preheat of approx. 150-300°C. When welding without preheat, use low heat input method.
Lightly peen weld beads during welding of thicker sections. On completion allow the workpiece to cool
slowly. The deposit is fully machinable.
Applications:
Spheroidal graphite, nodular and ductile cast irons e.g, machine bases, transmission housings, gear
boxes, engine blocks and pump bodies.
