Selectarc HBA

This is a basic, slag-free hardfacing electrode offering a high recovery rate (190%). Its high chromium and carbon content provides excellent abrasion resistance. The electrode deposits 1 or 2 layers and is suitable for applications requiring resistance to heavy mineral abrasion and moderate impact. The electrode features an austenitic matrix containing chromium carbides. It produces smooth, regular beads with consistent transfer and no slag formation. While crack formation in the weld deposit is normal for this type of composition, it’s crucial to follow recommended preheating and cooling procedures for optimal results.

Selectarc HBA is ideal for a wide range of applications demanding high wear resistance. Specifically, it is recommended for endless screws, mixer paddles, pump bodies for abrasive materials, excavator teeth, crushing mineral materials, concrete pumps, and screws for brick presses. It is also suitable for wear plates. When hardfacing tool steels, a cushion layer using Selectarc 29/9 or 18/8Mn and preheating to 200-400°C is highly recommended.
