CLASSIFICATION: EC16-8-2 per AWS A5.9

A gas-shielded, metal cored, stainless steel electrode, SelectAlloy 16-8-2-C has a nominal composition of 15.5% chromium, 8.5% nickel and 1.5% molybdenum.

APPLICATIONS: SelectAlloy 16-8-2-C may be used to weld 16-8-2, 316 and 347 grades of stainless steel in high temperature piping systems. It has good hot ductility properties and is well suited for welding cat crackers, furnace parts and components used in the petrochemical, chemical processing and power generation industries.

DIAMETERS: .045", 1/16"

SHIELDING GASES: Ar/1-2% O2, Ar/1-2% CO2, 40-55 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Delivers a smooth, spray arc transfer.
  • Produces little or no slag and virtually no spatter which minimizes cleanup.
  • Offers higher deposition rates and more controlled penetration than the equivalent solid electrode.
  • Operates at higher travel speeds and is better at handling poor fit-up.
  • Makes small butt, lap and fillet welds on thin material at elevated travel speeds.
