CLASSIFICATION: E80T1-Ni2C per AWS A5.29, ASME SFA 5.29

Select 81-Ni2 is a low alloy steel, gas-shielded, flux cored wire intended for the welding of carbon and low alloy steels requiring a minimum tensile strength of 80,000 psi and good CVN toughness at subzero temperatures.

APPLICATIONS: Due to its good charpy v-notch toughness and tensile strength, Select 81-Ni2 is an excellent choice for welding steels such as ASTM A203, A572, A575 and A734 as well as steels containing 2% nickel. Typical applications for this electrode include offshore platform construction, earthmoving and mining machinery and shipbuilding.

DIAMETERS: 1/16", 5/64", 3/32"

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Exceptional low temperature CVN toughness due to 2-2½% nickel in the weld deposit.
  • Smooth spray transfer.
  • Easily removed slag.
  • Smooth, rippled bead profile.
