LoTherme-625

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 35 GMT.

Characteristics

LoTherme-625 is characterized by producing easy work hardening and highly wear resistible austenitic 17%Cr-15%Mn- 3% Ni weld metal. The electrode possesses pleasing operating characteristics and produces smooth, well-rippled weld beads.

Applications

LoTherme-625 is ideally suited for welding high manganese steel such as rail crossings and points, jaw and roll crushers, crusher hammers, crushing blades, etc.

Typical Mechanical Properties Of All Weld Metal

Weld Metal Hardness : 200-300 BHN (As welded)

After work hardening : 400-470 BHN

Welding Technique

Keep the electrode dry. In case of moisture pick up, they should be rebaked 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
