CLASSIFICATION: E90T1-D3C per AWS A5.29, ASME SFA 5.29

Select 91-D3 is a gas-shielded, low alloy steel electrode intended to match the mechanical properties and corrosion resistance of certain pressure vessel steels. This electrode can be used for single and multiple pass welding in horizontal fillets and the flat position.

APPLICATIONS: Select 91-D3 is a manganese-molybdenum flux cored electrode which is well suited to weld steels such as ASTM A302 GrB and manganese-molybdenum castings such as ASTM A49, A291 and A735.

DIAMETERS: 1/16", 5/64", 3/32"

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Good welder appeal and excellent bead profile.
  • Low spatter levels.
  • High strength and corrosion resistance of deposit matches the appropriate steels.
