CLASSIFICATION: EC307 per AWS A5.22

SelectAlloy 307-C is a composite, metal cored electrode for gas metal arc welding of stainless and certain types of other austenitic steels. The composite nature of this metal cored electrode provides higher deposition rates and faster travel speeds than those achieved by solid wires.

APPLICATIONS: SelectAlloy 307-C is a superb choice for joining austenitic stainless to ferritic stainless or carbon steel, ferritic to ferritic stainless or other dissimilar metals. This electrode is widely utilized in welding automotive exhaust systems as well as armor plate, austenitic manganese steel, dissimilar steels and as a buttering layer prior to hardsurfacing.

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

SHIELDING GASES: Ar/1-2% O2, Ar/1-2% CO2, 40-55 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Quite resistant to hot cracking.
  • Stable arc transfer transitions easily to spray.
  • Higher deposition rates and faster travel speeds than solid wire.
  • Bridges gaps and poor fit up areas well.
