Low heat input, low hydrogen electrode having excellent resistance to abrasion at elevated temperature.
• Low heat input, low hydrogen, Ni-Mo alloy based electrodes.
• Electrode producing a weld metal having exceptional resistance to wear to combat abrasion, impact, and retain hardness at elevated temperatures.
• Soft and stable arc, which is easy to strike and re-strike.
LoTherme-624 BE is ideally suited for hardfacing machine parts and components subject to combination of heavy abrasion, metal-tometal wear, moderate impact and hardness at elevated temperatures. Typical applications include surfacing such as hot shears, blast furnace bells, tong teeth, hoppers, valve seats, guide plates, etc.
As Deposited : 50 - 53 RC
At 550°C : 40 - 43 RC
Remove all damaged and fatigued metal before deposition. Use short arc and stringer bead technique. Keep the electrodes dry. In case of moisture pick-up, redry at 250°C for an hour before use.
