Application field UTP 75 is, due to the high hardness, particularly suited for hardfacing of parts subject to extremely severe mineral abrasion with very low impact stress, such as sand mixer blades, conveyor screws in the ceramics industry, earth drills, injection screws of brick moulding machines, teeth and bars of grates in the steel industry, bucket and shovel teeth, strippers on asphalt processing machines, trench milling tools. Welding properties UTP 75 has a smooth and stable arc and a self-removing slag. The smooth bead surface does, in most cases, not require any machining by grinding with silicon carbide or diamond wheels. Hardness of the pure weld deposit : approx. 65 HRC Microhardness of the tungsten carbides : approx. 2500 HV
