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.
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.
LoTherme-619 is ideally suited for welding high manganese steel such as rail crossings, Bulletproof steel plates, Crushing blades, Crushing hammers etc.
Weld metal Hardness : 240-250 BHN (As welded)
After work hardening : 400-470 BHN
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 Range (Amps)||160-200||140-180||100-140||70-90|
