SelectAlloy 308H-AP is a gas-shielded, flux cored, all position, stainless steel electrode with a nominal weld metal composition of 20% chromium, 10% nickel and a carbon content of .04-.08%. The higher carbon in this alloy makes it well suited for higher temperature use.

APPLICATIONS: SelectAlloy 308H-AP is utilized in the welding of components for the petrochemical industry. It may also be used to weld 304H and 347H.

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

SHIELDING GASES: 100% CO2, 75-80% Ar/balance CO2, 40-55 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Superb all position performance qualities.
  • Achieves flat, well washed beads with minimal weaving.
  • Spatter is very low.
  • Excellent slag peeling minimizes cleanup.
