Select 910-B91

Low Alloy / Flux Cored / Gas Shielded


Features

  • Designed for welding 9Cr-1Mo steels in all positions
  • Contains small additions of niobium, vanadium, and nitrogen to improve long term creep properties.
  • Provides smooth and stable arc transfer, producing uniform beads that tie-in nicely.
  • Used to weld creep resistant steels such as: A387 Gr 91 plate, A335 P91 and A369-FP91 piping, A199-T91, A200-T91, A212-T91 tubing, A182-F91 forgings, as well as other 9Cr-1Mo fittings and castings.
  • Typical applications include power plant turbine casings, valves, headers, and piping.
