Select Ni4S

Low Alloy / Submerged Arc / Flux Shielded


Features

  • Contains additions of nickel and molybdenum to produce good low temperature toughness while maintaining a tensile strength that withstands heat treatment.
  • Better control of bead penetration than solid wire
  • Higher deposition rates than solid wire when run at the same current level
  • Exhibits a broader and shallower bead profile than 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 clean up time
  • Typical applications include pressure vessels, offshore oil equipment, bridges, and other structural applications
  • Arcflux BF-10MW helps to maximize the impact properties and is the recommended flux. Other basic fluxes can be used as well.
