GEEFLUX 303 X GEESAW 410 NiMo

SPECIFICATION : JIS Z3324 FSS-B1/YS308 (L)

CHARACTERISTICS :

Agglomerated neutral basic flux for welding austenitic stainless steel and heat resistance steels.It’s behavior as to carbon of the weld metal is strictly neutrall.Excellent weldability such as stable arc and easy slag removal, uniform bead appearance.

Main constituents :

SiO2 Al2O3 CaF2
10% 35% 50%

APPLICATION:

 Welding surfacing of various rolls of steel  plants such as wet rolls, caster rolls etc.

MECHANICAL PROPERTIES OF THE WELD METAL (RANGE)

Hardness of the deposited weld metal:

32-38 HRc 

SPECIAL INSTRUCTIONS:

  • Dry the flux at 3000C –3500C for 1 hour before use.
  • Avoid using high current to prevent harming of corrosion- resistbility in heat-affected zone. Heat-input in welding should be kept as low as possible.
  • Welding in groove should be done in 2 passes for ease slag removal.
  • Preheat and interpass temperature 150°C-250°C
  • PWHT: 600°C for 2 to 6 hrs depends upon thickness of the rolls
