CLASSIFICATIONS: E307T1-1, E307T1-4 per AWS A5.22

SelectAlloy 307-AP is a gas-shielded, flux cored, stainless steel electrode which is composed of a nominal weld metal of 19% chromium, 10% nickel, 4% manganese, 1% molybdenum and a carbon content of 0.08%. This wire’s relatively high manganese content helps reduce the chance of weld metal cracking in dissimilar metal welding.

APPLICATIONS: SelectAlloy 307-AP is an excellent choice for joining difficult-to-weld steels, such as armor plate and hardenable steels, and for dissimilar metal joints, such as austenitic manganese steels to carbon steel forgings and castings.

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

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

WELDING POSITIONS: All Positions

CHARACTERISTICS:

  • Delivers superb performance characteristics in all positions.
  • Spatter is low and slag peeling is easy.
  • Achieves flat, well-washed beads with minimal weaving.
