Description¡G
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 200¢J is
appropriate to prevent cracking. Lowe cooling is
recommended after welding.
