CLASSIFICATIONS: E309LMoT1-1, E309LMoT1-4 per AWS A5.22

This gas-shielded, flux cored, all position, stainless steel electrode is nominally composed of 23% chromium, 13% nickel, 2.5% molybdenum and a maximum carbon content of .04%. The molybdenum provides increased resistance to pitting corrosion. The low carbon minimizes carbide precipitation and makes the weld metal more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 309LMo-AP is designed for welding in the pulp and paper industry, chemical processing equipment and food and beverage equipment. It is used to join carbon and low alloy steels to molybdenum-containing austenitic stainless steels, for root passes in cladding applications and to join difficult-to-weld or dissimilar steels.

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

SHIELDING GASES: 100% CO2, 75-80% Ar/balance CO2, 40-55 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Achieves flat, well washed beads with minimal weaving.
  • Produces very low spatter.
  • Outstanding slag peeling reduces cleanup time.
