CLASSIFICATIONS: EC308L per AWS A5.22
(Also meets EC308 per AWS A5.22)

APPROVAL: CWB EC308L

A gas-shielded, metal cored, stainless steel electrode, SelectAlloy 308L-C provides a nominal weld composition of 21% chromium, 10% nickel and a maximum carbon content of 0.03% to minimize carbide precipitation and resist intergranular corrosion.

APPLICATIONS: SelectAlloy 308L-C is ideally suited for making small butt, lap and fillet welds on thin material at elevated travel speeds. It may be used to weld 301, 302, 304L, 308 and 308L grades of stainless as well as Types 321 and 347 (as long as the service temperature does not exceed 500°F). Typical applications are in-welded components for the chemical, paper, textile and pharmaceutical industries and food service equipment.

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

SHIELDING GASES: Ar/1-2% O2, Ar/1-2% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Higher deposition rates and more controlled penetration than solid wire.
  • Operates at higher travel speeds and handles poor fit up.
  • Provides a smooth, spray arc transfer.
  • Produces little or no slag and virtually no spatter.
