An outstanding low heat input, hard-facing electrode having excellent resistance to abrasion, metal-to-metal wear at ambient as well as at high temperatures and good corrosion resistance.
LoTherme-613 yields weld deposits, which have excellent resistance to abrasion and metal-to-metal wear in combination with good resistance to corrosion. The weld deposits possess hardness of 48- 56 RC. Hardness is retained up to 550°C. A soft and stable arc, which is easy to strike and restrike, good slag detachability and smooth weld profile are some of the many pleasing features associated with LoTherme-613.
Where conditions are highly abrasive and also corrosive e.g. flue gases, slurries, etc., LoTherme-613 is the most appropriate electrode.
The capacity to retain hardness at high temperatures, and excellent resistance to abrasion make LoTherme-613 ideally suited for surfacing blast furnace bells and hoppers, conveyor screws, coke, chutes, steel mill grinders, pump impellers, valves, etc.
Weld Metal Hardness : 48 - 55 RC
For best result, bake the electrodes at 200°C for one hour before use. Clean weld surface thoroughly free of all surface contamination. Use short arc and stringer bead technique.
