Description?G
The
C-309Mo is a lime-titania type electrode for all
position welding. Which has good usability and good weld
ability. Good resistance against dilute sulfuric acid
compared with that of C-309Mo. Weld metals provide
excellent corrosion resistibility and heat resistibility
in the as-weldded condition.
Application?G
For welding 22%Cr-12%Ni
stainless steel . For build up welding of Cr-Mo steel or
carbon steel. For welding of SUS 316 to carbon steel.
Clad steel side welding to SUS 316 or SUS 316L.
