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.
