ES EST is a non-nickel, non machinable cast iron electrode.
It is the most economical way to go for repairing various kinds of cast iron products providing that machinability of the weld deposit is not required and where weld shrinkage stress is not a concern.
EST melts at relatively low temperatures which permit the use of low welding currents.
This electrode may be used in any position utilizing AC or DC (reverse polarity).
