YAWATA H-650 (For Earth and Sand Abrasion)
Classification : DIN 8555 : E 6-UM-60
Approvals : -
Application : Surfacing of Crusher parts, dipper teeth, shovel teeth, etc.
YAWATA H-650 is a low hydrogen type electrode for surfacing worn parts of various machinery to be used without machining. Deposited metal of about 700 Vickers hardness and martensitic structure provides excellent resistance to earth and sand abrasion.

1. Use dry electrodes only. Damp electrodes should be re-dried at 300～350℃ for 60 minutes before use.
2. Preheating at more than 150℃
3. A buffer layer with low hydrogen electrode is required to surface hardening metal or to deposit multiple layer.
