Select EA3K-S

Low Alloy / Submerged Arc / Flux Shielded


Features

  • Designed to deposit high manganese weld metal with roughly 0.5% molybdenum added to increase strength, especially at elevated temperatures.
  • Higher deposition rates than solid wire when run at the same current level
  • Exhibits a broader and shallower bead profile than when using solid wire, reducing the tendency for burn through
  • Capable of running directly over root passes with proper procedure – eliminating requirement for a hot pass
  • Easy slag removal – reduces post weld cleanup time
  • Arcflux BF-10MW is the recommended flux, although other neutral fluxes with high basicity can be used as well.
