CLASSIFICATIONS: E91T1-K2C, E91T1-K2M per AWS A5.29, ASME SFA 5.29

Select 910-K2 proves an ideal selection for weldments requiring 90,000 psi minimum tensile strength and good CVN toughness values. This gas-shielded, flux cored electrode is intended for single and multiple pass welding of certain low alloy steels in all positions.

APPLICATIONS: Typically, these involve the steels used in the fabrication of submarines, offshore platforms and leg assemblies, earthmoving machinery and specialized structural applications. These steels are usually types such as HY-80, HY-100, ASTM A710, A514 and other similar high strength steels.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 100% CO2, 75-80% Ar/balance CO2, 35-50 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Good subzero CVN toughness.
  • Rutile based slag system facilitates all position welding.
  • Exceptional weld bead geometry.
  • Smooth spray arc transfer with low spatter.
