Fonweld E713
FONWELD E 713
Type: Manganese steel electrode with basic coating
DIN 8555: E 7 – 250 k coated
AWS: E Fe Mn – A covered
Applications:
- Build-up of wear resistant manganese steel layers on steel and hard manganese steels, on excavator teeth, beater mills, crusher jaws, crusher heads, manganese steel rails, beater arms. The workpiece should not be allowed to get too hot during welding; interrupt as necessary to allow cooling down.
Characteristics:
- Ductile weld metal of austenitic structure, can be work-hardened to reach hardness values of up to 55 RC . Very good service life is attained in conditions of simultaneous exposure to shocks and abrasive wear. Only use dry electrodes; redrying: 2 h/300 - 350°C.
Current mode: DCEP
