Select Ni1S Close Window
 Print Sheet


CLASSIFICATIONS: ECNi1 per AWS A5.23, ASME SFA 5.23
(Meets AWS A5.23, class F7A6-ECNi1-Ni1 when used with OP121TT Flux
)

This metal cored, low alloy wire, intended for the single and multiple pass welding of carbon and low alloy steels, is formulated for submerged arc welding only. Select Ni1S contains 1% nickel to produce good low temperature toughness.

APPLICATIONS: Select Ni1S is designed for those applications where low temperature toughness is required such as offshore oil equipment, shipbuilding and other cold weather structural applications.

DIAMETERS: 3/32", 1/8", 5/32"

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Excellent low temperature toughness.
  • Better bead control and higher deposition rates than solid wire.
  • Broader and shallower penetration patterns.
  • Reduced "burn-through" tendency.
