Cast Iron

JACKSUN CAST STEEL

AWS: Est. (A5.15) Est.

JACKSUN CAST STEEL electrodes are designed for welding cast iron and cast steel components.
They are ideal for repairing broken castings, joining cast iron to steel, and overlaying wear surfaces.
The electrodes provide excellent arc stability, low spatter, and minimal cracking during welding.
