CLASSIFICATIONS: EC309L per AWS A5.22
(Also meets EC309 per AWS A5.22)

APPROVALS: CWB EC309L

SelectAlloy 309L-C's low carbon content minimizes carbide precipitation and makes the weld metal more resistant to intergranular corrosion. This gas-shielded, metal cored, stainless steel electrode is composed of 24% chromium, 13% nickel and no more than 0.03% carbon.

APPLICATIONS: SelectAlloy 309L-C is used to weld Type 309 stainless steel, to join carbon and low alloy steels, to weld 304 and for the first layer cladding of carbon steel. This wire is designed for welding refinery and chemical processing equipment and furnace and auto exhaust parts.

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

SHIELDING GASES: Ar/1-2% O2, Ar/1-2% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Higher deposition rates and travel speeds than solid wire.
  • Smooth spray arc transfer.
  • Produces virtually no spatter and little or no slag.
  • Handles poor fit up.
