Print Sheet  


CLASSIFICATIONS: E316LT0-4 per AWS A5.22

SelectAlloy 316L CRYO is a gas-shielded, flux cored, stainless steel electrode with a nominal weld metal composition of 19% chromium, 12.5% nickel, 2.5% molybdenum and a maximum carbon content of 0.04%. This wire is designed for cryogenic applications where good weld metal toughness is needed.

APPLICATIONS:SelectAlloy 316L CRYO is used in the fabrication and repair of cryogenic components in applications which require weld metal toughness at liquid nitrogen temperatures (-320 ºF).

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

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

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces a finely rippled, even and well washed bead.
  • The arc transfer is smooth with minimal spatter.
  • Cleanup is minimized due to the freely peeling slag.
