SelectAlloy 307EU-C close window
Print Sheet 


CLASSIFICATION: No AWS class. Conforms to European Standard EN12073, Class T 18 8 Mn M M.

Designed to provide higher deposition rates and faster travel speeds than solid electrodes, the composite, metal cored SelectAlloy 307EU-C is intended for the gas metal arc welding of stainless and certain types of other austenitic steels. This wire may also be used to weld armor steels and ferritic stainless steels in certain applications.

APPLICATIONS: SelectAlloy 307EU-C is an excellent choice for welding automotive exhaust systems, especially when joining austenitic stainless to ferritic stainless or carbon steel, ferritic to ferritic stainless or other dissimilar metals within the exhaust system. European auto manufacturers often specify Type 307 to this specification.

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

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

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Resists hot cracking.
  • Consistent deposit composition due to even distribution of core ingredients.
  • Higher deposition rates and faster travel speeds than solid wire.
  • Stable arc transfer transitions easily to spray.
  • Bridges gaps and poor fit up areas well.
