A unique electrode for surfacing of valves & valve seats, steel plant hot metal rolls.
LoTherme-444H is ideally suited for surfacing components subjected to high temperature metal to metal wear, corrosion, erosion combined with abrasion. Typical applications include rebuilding of runners, hardfacing of valves & valve seats, pulp & paper machinery, continuous casting rolls & rolls subjected to high temp in steel Rolling mills.
Weld Metal Hardness : 400 - 500 BHN As Welded.
Keep the electrodes dry. In case of moisture pick up, they should be re-dried at 200-250°C for one hour. Clean the weld area throughly free of any foreign matter. Use low current, short arc and stringer beads.
