IDENTIFICATION
GRINOX 9Mo E309 Mo-16
CLASSIFICATION
AWS/SFA 5.4: E309Mo-16 IS: E23.12.2 R 26
DESCRIPTION
An extruded, rutile based heavy coated electrode giving 25 Cr / 12 Ni / 2.5 Mo type stainless steel deposit. The arc is soft & stable with easy strike and restrike. Low spatter and easily detachable slag. Weld bead is finely-rippled. Addition of Molybdenum improves tensile strength and corrosion resistance. Weld metal is resistant to temperatures upto 1100°C.

TYPICAL APPLICATIONS
• For welding AISI 309, 309 Mo, 316 type of stainless steels of steels clad with such materials.
• Also suitable for joining Molybdenum containing high alloyed and unalloyed steels.
• Used for welding difficult to weld steels and for building up carbon steel to improve its wear resistance.
• Applicable for For AISI 309, 309-Mo, 316 type stainless Steels or Molybdenum containing high alloyed steels and unalloyed steels.
WELDING PROCEDURE
The base metal should be free from oil, Grease or Dirt before welding. Keep a short arc and avoid weaving. Weld is to be cleaned with stainless steel brush.
