LoTherme-619

AWS: SFA
EN ISO CODE:

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.

Approvals
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.

Weld Metal Hardness

As Welded : 230-260 BHN

Work hardens under impact up to : 400-470 BHN

Welding Technique

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

Current Conditions : DC (+) /AC
