AWS ESt

DescriptionG

E-St is a graphite type electrode using mild steel core rod. Its weld metal shows high carbon content. Then it results high hardness, so it is suitable for welding the parts where machining is unnecessary. Its fusibility with cast iron is excellent.

Application :

For repairing of cast iron parts where machining is unnecessary.

Instructions for welding :

The preheat temperatures vary in accordance with kind, shape and size of base metal. Preheating over 200J is appropriate to prevent cracking. Lowe cooling is recommended after welding.
