GRINOX 9MO

IDENTIFICATION : GRINOX 9Mo E 309 Mo-16
SPECIFICATIONS : AWS/SFA 5.4: E 309 Mo 16 IS : E 23.12.2 R 26

CHARACTERISTICS :

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 APPLICATION :

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.
