Print Sheet 


CLASSIFICATION: E309LCbT1-1, E309LCbT1-4 per AWS A5.22

This all position, gas-shielded, flux cored electrode has a nominal weld metal composition of 23.5% chromium, 13% nickel, .8% columbium and a maximum carbon content of .04%. The columbium in SelectAlloy 309LCb-AP forms a stable carbide and makes the weld metal more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 309LCb-AP is used to overlay carbon and low alloy steel. This electrode will produce a columbium stabilized first layer.

DIAMETERS: .035", .045", 1/16"

SHIELDING GASES: 100% CO2, 75-80% Ar/ balance CO2, 40-50 cfh

WELDING POSITIONS: All Positions

CHARACTERISTICS:

  • Spatter is very low.
  • Reduces cleanup time due to outstanding slag peeling.
  • Minimal weaving required due to flat, well-washed beads.
  • Resists intergranular corrosion.
