Description¡G
The C-86B2
is an outstanding welding electrodes for higher strength
steels with tensile strengths greater than 80,000
pounds. 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
electrode with operator appeal.
Application¡G
The C-86B2 is used for
fabrication and maintenance of boilers and association
piping . Such steels as 11/4Cr-1/2Mo, and 1/2Cr-1/2Mo,
are properly welded with 8016B2.
