OK Weartrode 62 (formerly OK 84.84) is a hardfacing electrode depositing a weld metal with a high volume fraction of fine carbides in a martensitic matrix.
It is designed for the protection of components subjected to severe abrasive wear.
Typical applications: earth-drilling equipment, hammers, scrapers and knives, shovel buckets and shovel teeth.
Recommendation: Preheating is normally not required, except for heavier sections where preheating to 200°C may be beneficial.
Stringer beads are recommended. Optimum hardness is obtained in the first layer due to low dilution with the parent material
