Description：
The C-309L
is a lime-titania type electrode for all position
welding.
As weld metal contains ferrite in austenitic structure.
Its weld ability is good and it provides good corrosion
resistibility and good heat resistibility.
As weld metal contains much quantity of alloying
elements and has stable austenitic structure, it is
suitable for welding of the part which is affected by
the dilution of mother plate.
Application：
For welding 22%Cr-12%Ni
stainless steel (SUS 309S etc.)and welding stainless
steel to mild steel or low alloy steel.
Welding of dissimilar metals such as stainess steel to
mild steel or low alloy steel.
Clad steel side welding to SUS 304L. Under laying
welding of SUS 304L to carbon steel or low alloy steel.
