Conforms to Certification: AWS A5.23                   ASME SFA A5.23

Weld Process: Submerged Arc Welding Process

AWS Chemical Composition Requirements
C = 0.07 -0.15 P = 0.025 max
Mn = 0.45 – 1.00 Cr = 1.00 – 1.75
Si = 0.05 – 0.30 Mo = 0.45 – .065
S = 0.025 max Cu = 0.35 max

Available Sizes:
3/32 x 55c
1/8 x 55c
5/32 x 55c

Application
EB-2 is used for submerged arc welding of 1 ¼ chrome, ½ 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 and consequently its corrosion resistance and mechanical properties.

Deposited Chemical Composition % (Typical)
C = 0.10 S = 0.008 Mo = 0.54
Mn = 0.65 P = 0.010 Cu = 0.21
Si = 0.25 Cr = 1.45

Note: Using Neutral flux

Deposited All Weld Metal Properties % (AW)
