For Hard-Facing, Wear-facing or Overlay Applications

LoTherme-619

Low heat input hard-facing electrode for reconditioning of worn-out MM steel and Gr. 90A points and crossings for use in high traffic density routes.

Characteristics

LoTherme-619 has been formulated to produce strong, tough, easy work hardening and highly abrasion resistible austenitic 15Cr-15Mn- 2Ni weld metal. The electrode possesses pleasing operating characteristics and produces smooth, well-rippled weld beads, with easy slag detachability.

Applications

LoTherme-619 is ideally suited for welding high manganese steel such as rail crossings, Bulletproof steel plates, Crushing blades, Crushing hammers etc.

Typical Mechanical Properties Of All Weld Metal

Weld metal Hardness : 240-250 BHN (As welded)

After work hardening : 400-470 BHN

Welding Instructions

Keep the electrode dry. In case of moisture pick up, they should be rebaked at 250°C for min. one hour. Clean the weld area thoroughly free of any foreign matter, Use low current, short arc and stringer beads,

Current Conditions : DC (+) /AC
