Approvals
Characteristics

LoTherme-625 is characterized by producing easy work hardening and highly wear resistible austenitic 17Cr - 15Mn - 3Ni 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.

Weld Metal Hardness

As Welded : 200-300 BHN

Work hardens under impact up to : 400-470 BHN

Welding Technique

Keep the electrode dry. In case of moisture pick up, re-dry 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
