CLASSIFICATIONS: E80T5-Ni3M-H4 per AWS A5.29, ASME SFA 5.29
Select 85-Ni3 is a low alloy steel, gas-shielded, flux cored electrode for single and multiple pass welding of certain HSLA steels. It produces a weld deposit that contains about 3.5% nickel to enhance low temperature toughness.
APPLICATIONS: Select 85-Ni3 is designed to weld 3% Ni steels that require a postweld stress relief, a minimum of 80,000 psi tensile strength and outstanding low temperature toughness. Applications include shipbuilding and tanks used for gas storage.
DIAMETERS: .045”, 1/16”
SHIELDING GAS: 75-80% Ar/ balance CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Excellent low temperature toughness.
Low diffusible hydrogen levels.
Basic slag system with globular arc transfer.
Bead profile is convex.
