Description?G
These
electrode are stainless steel electrodes depositing weld
metal of 19%Cr-9%Ni-Nb austenitic stainless steel. The
deposited metal has a minimum chromium carbide
precipitation because of Nb and has an excellent
resistance to inter granular corrosion. Also, it has a
good acid resistibility and head resistibility.
Therefore, it has the most excellent creep strength at
elevated temperature. This electrode is suitable for
welding of chemical plants, boilers and gas turbines,
etc.
Application?G
Used for welding of
AISI347 or AISI321. Also, it is suitable for welding of
boilers and gas turbines.
