YAWATA H-600 (For Metal to Metal Heavy Abrasion & Sand Abrasion)

Classification : DIN 8555 : E 3-UM-600

Approvals : TIS

Applications : Surfacing of track rollers, crusher teeth, mill hammers and bucket lips.

Property

YAWATA H-600 is a hardfacing type electrode for surfacing worn parts of civil engineering, construction and mining machinery to be used without machining. Deposited metal of about 600 Vickers hardness and martensitic structure provides high toughness in spite of high hardness and excellent abrasion resistance to medium impact.

Recommendations for Use

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℃ is required.
3. A buffer layer with low hydrogen electrode is required to surface hardening metal or to deposit multiple layers.
