Select 91-B3

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Formulated for the welding of certain high temperature, creep resistant materials in the flat and horizontal position.
  • Rutile slag system provides good welder appeal and bead geometry
  • Deposit composition is nominally 2 1/4″ chromium, 1% molbdenum, making it the ideal choice for welding materials such as:ASTM A387 Gr. 22 plate or A335 P22 pipe, which are commonly used in the fabrication of pressure vessels, boilers, heat exchangers, and other applications involving high temperatures that require creep resistance.
