For Hard-Facing, Wear-facing or Overlay Applications
LoTherme-618
AWS: SFA
EN ISO CODE:
Low heat input hardfacing electrode having outstanding abrasion, erosion resistance at high temperatures.
• Specially formulated to retain abrasion, erosion resistance up to 650°C.
• Excellent resistance to wear due to high temperature Abrasion & Erosion.
• Soft and stable arc which is easy to strike and re-strike.
• Easy handling with rapid deposition rate.
• Thick single pass deposits give extra high yield.
LoTherme-618 is a specially designed for hard-facing carbon steel and austenitic manganese steels for applications encountering abrasion and erosion at elevated temperatures. The typical applications include clinker conveyor chains, sinter handling equipment, coke pusher shoes, augers, slurry pumps, billet conveyor guide, hot slag conveyors, etc.
57 - 63 RC
In case of moisture pick-up, re-dry the electrodes at 200°C for one hour before use. Remove all damaged and fatigued metal and clean weld area. Use short arc and stringer bead technique. For high carbon steels, hardfacing use preheat up to 275°C. For austenitic manganese steels do not allow temperature of parts to rise more then 150°C and use LoTherme-457 as a cushion layer. Slow cool after welding.
