  • Excellent operating characteristics.
  • Weld metal having excellent crack resistance.
  • Weld metal possesses excellent resistance to corrosion, erosion, pitting, & abrasion.
Applications

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.

Typical Mechanical Properties Of All Weld Metal

Weld Metal Hardness : 400 - 500 BHN As Welded.

Welding Technique

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.
