Grain Size : 8 X 60 BSS
CHARACTERISTICS :
Raajmelt-spl is an agglomerged aluminates basic type submerged arc welding flux for very high current carrying on AC and DC. It is used with operational properties for single double and multi wire system. It gives impact resistance sub zero and minus temperature. The flux can be used with EL8,EM12K, EH14 and EA2.
TYPICAL APPLICATION :
Raajmelt-spl suitable for fillet welding and single or multi pass butt welding with low, medium and high tensile steels. Single wire tandem and multi-wire welding is possible for increased productivity
Drying requirement :
Redrying recommended at 250-300°C for one hour before use.
