CLASSIFICATIONS: E81T1-B2C per AWS A5.29, ASME SFA 5.29

Select 810-B2 is a low alloy steel electrode designed for single and multiple pass welding, in all positions, of certain chromium-molybdenum steel plate and pipe where 1 1/4% Cr and 1/2% Mo are required in the weld deposit.

APPLICATIONS: Select 810-B2 is formulated to weld steels subject to high temperature service such as A387 Gr. 11 plate and A335 P11 pipe. These materials are used in the fabrication of boilers, heat exchangers and pressure vessels.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Superb welder appeal with excellent mechanical properties.
  • Low spatter emission.
  • Fast freezing slag removes easily.
  • Resists creep and maintains strength at elevated temperatures.
