LoTherme-616

Electrode for resisting high abrasion wear with moderate impact at 450°C.

Characteristics

LoTherme-616 is a high Niobium-Chromium Carbide alloy specially designed to resist high stress grinding abrasion wear with moderate impact, even at elevated temperature of 450°C. The deposit will exhibit surface relief checks.

Applications

It is suitable for welding of conveyor screws, VRM tyres, Coke chutes, coal mill exhaust fan blades, table liners, screens, oils expeller screws, etc.

Typical Mechanical Properties Of All Weld Metal

WELD METAL HARDNESS : 56 - 62 HRC

Welding Technique

Remove all the damaged and fatigued metal and clean weld area. Use short arc and stringer bead technique. For High Carbon Steels use preheat up to 300°C. For austenitic manganese steels do not allow the temperature of parts to exceed 150°C and use LoTherme-457 as cushioning layers. Slow cool after welding.
