CLASSIFICATION: E90T1-K2C per AWS A5.29, ASME SFA 5.29

Select 91-K2 is a premium low alloy, gas-shielded, flux cored electrode designed for those applications requiring 90,000 psi minimum tensile strength and good low temperature toughness.

APPLICATIONS: Select 91-K2 is utilized for welding steel types which include HY-80, HY-100, ASTM A710, A514 and other similar high strength, low alloy steels. These generally involve the fabrication of offshore platforms and leg assemblies, earthmoving machinery and specialized structural applications.

DIAMETERS: 1/16”, 5/64”, 3/32”

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Provides moderate high tensile strength and good low temperature toughness.
  • Produces a smooth arc transfer with a thin coverage of easily removed slag.
  • Offers smooth, rippled bead profile.
