CLASSIFICATIONS: E81T1-B2LC per AWS A5.29, ASME SFA 5.29
Select 810-B2L is a premium low alloy steel electrode intended for
single and multiple pass, all position welding of certain 1 1/4
percent chromium and 1/2 percent molybdenum steel plate and
pipe, where lower carbon levels are required in the weld deposit.
APPLICATIONS: Select 810-B2L is specially designed to weld
thin-walled A335-P11 pipe or tube and is well suited for use in
the fabrication of pressure vessels, heat exchangers and boilers.
DIAMETERS: .045", .052", 1/16"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: All positions
CHARACTERISTICS:
- Smooth arc transfer.
- Low spatter emission.
- Fast freezing slag removes easily.
- Provides improved ductility and lower hardness over conventional, higher carbon grades.
