General characteristics

It is designed for open-arc cladding of parts operating under conditions of intensive abrasive wear in combination with moderate impact loads and corrosive environment.

Application

Typical applications are as follows: cladding of extruder screws and sleeves, excavator bucket teeth, parts for crushers, scraper working edges, wear-resistant plates, dredge pumps, mixer blades and parts of sea dredger ships and graders etc.
