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.
