Description¡G
The C-98B3
is outstanding welding electrode for welding higher
strength piping, castings and forgings. The coating is
specially formulated to resist moisture pickup under
conditions of high heat and humidity. This electrode
offers resistance to moisture reabsorption which helps
prevent hydrogen cracking and aids in elimination of
starting porosity. Definitely a preferred electrode with
high operator appeal.
Application¡G
The C-98B3 is used in
welding chrome-moly pipes and boiler work.
