SelectAlloy 307T0-3

Stainless Steel / Flux Cored / Self Shielded


  • The relatively high Mn content of ~4 wt% helps reduce the chance of weld metal cracking in dissimilar metal welding.
  • Designed for welding in either the flat or horizontal position where gas-shielding is not possible.
  • Arc transfer is globular, with low spatter, and resulting bead is flat and well washed with a fine ripple surface.
  • Applications for this alloy includes joining difficult to weld steels, hardenable steels, and dissimilar steels, such as welding armor plating and austenitic manganese steel forgings or castings.
