Low heat input electrode depositing low carbon high Cr - high Ni - Mo -Cu weld metal.
LoTherme-483 is a special DC (+) electrode producing a low carbon Cr-Ni-Mo-Cu weld metal which resists Sulfuric acid, Phosphoric acid corrosion environment. It is characterized by quite and stable arc, which is easy to strike and restrike, finely rippled smooth weld beads and good slag detachability.
LoTherme-483 is ideally suited for welding similar composition materials to itself and to other grades of stainless steels.
ULTIMATE TENSILE STRENGTH : 54 Kgf/mm2
ELONGATION (L=4d) : 34 %
Welding zone must be clean and free from residues, such as grease, paint or metal dust. Use stringer beads, short arc and smallest possible size, which helps in reducing the heat input. The electrodes should be kept dry. Redry the electrodes at 200-250°C for one hour before use.
