CLASSIFICATION: EC316LSi per AWS A5.22

SelectAlloy 316LSi-C is a gas-shielded, metal cored, stainless steel electrode with a nominal weld composition of 19% chromium, 12.5% nickel, 2.5% molybdenum, 0.8% silicon and a maximum carbon content of 0.03%. The presence of molybdenum improves resistance to pitting and provides increased creep resistance. The low carbon content minimizes carbide precipitation and makes it more resistant to intergranular corrosion. In addition, the augmented silicon content improves bead wetting and produces a cosmetically appealing weld.

APPLICATIONS: This wire is ideally suited for making small butt, lap and fillet welds on thin material at elevated travel speeds. It is utilized to weld Type 316 stainless and other similar alloys, such as ASTM A743, and A744, Types CF-8M and CF-3M. SelectAlloy 316LSi-C is widely used in the pulp and paper industry, chemical and textile processing equipment, furnace parts and in parts exposed to marine environments.

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

SHIELDING GASES: Ar/ 1-2% O2, Ar/ 1-2% CO2, 40-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces smooth, well washed beads.
  • Offers higher deposition rates and more controlled penetration than the equivalent solid wire.
  • Operates at higher travel speeds.
  • Handles poor fit up.
  • Provides a smooth, spray arc transfer.
  • Produces little or no slag and virtually no spatter.
