Application
EB-3 is used for submerged arc welding of 2 ¼ chrome, 1 moly steels.
Note:Both agglomerated and fused fluxes can be used for submerged arc welding.
Note: The chemical composition of the flux mainly affects the chemistry of the weld metal.

Deposited Chemical Composition % (Typical)
C = 0.09 P = 0.009 Mo = 1.02
