GEMET 209

CHARACTERISTICS :

A rutile coated electrode depositing austenitic / ferritic stainless steel weld metal with a ferrite content of approximately FN 40. The weld metal exhibits excellent tolerance to dilution from dissimilar and difficult to weld materials without hot cracking.

TYPICAL USES:

Difficult to weld steels e.g. high carbon harden able tool, die and spring steels, 13 % Mn steels, free cutting steels, high temperature steels, dissimilar joints between stainless and high carbon steels, surfacing metal-to-metal areas, hot working tools, furnace components

HARDNESS OF THE UNDILUTED WELD METAL: 180-240 Brinell

OUTSTANDING FEATURES:

  • Spray type metal transfer.
  • Smooth weld bead, electrode does not get red hot.
  • Easy de-slagging.
  • Very low spatter loss, soft arc.
  • Excellent weld ability for all steels.

WELDING PROCEDURE:

  • Clean weld area.
  • Bevel heavy sections.
  • Use recommended current.
  • Dry the electrodes at 200°C/2 hrs.
  • Use short arc.

CORROSION RESISTANCE:

Good resistance to sulphurous gases at high temperature. Good resistance to wet corrosion upto approximately 300°C.
