Select 920-K2

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Produces weld metal with improved low temperature toughness when compared to other electrodes of the same class.
  • Exhibits a spray-like arc transfer with very little spatter.
  • Slag volume is moderate and removal is quite easy.
  • Ideal for applications requireing 90,000 psi minimum tensile strength with good subzero CVN toughness values.
  • Used to weld HY-80, HY-100, ASTM 710, A514, and other similar high strength steels.
  • Utilized in the fabrication of naval vessels, offshore platforms/leg assmblies, earthmoving machinery, and specialized structural applications.
