Description：
The C-318
is a lime-titania type electrode for welding of
18%Cr-12%Ni-Nb or Ti stainless steel. As containing of
Mo, it is resistibility against non-oxidizing acid like
dilute sulpuric acid and superior property can be
obtained against inter granular corrosion due to
containing of Nb.
Application：
For welding of
18%Cr-12%Ni-Mo-Nb or Ti stainless steel.
