Tungsten Carbide Steel Plate

PTA is a true welding process, with deposits forming a metallurgical bond with the base metal. The dilution level of Wear Plate by Plasma Transfer Welding is very close to those obtained by using the oxy-acetylene process.

The great advantage of using the PTA process is the capability of producing thin edge surfaces. While the hard facing provides the premier wear-resistant surface capable of working in all applicable service conditions at either ambient or elevated temperatures.

Together with the very low dilution (approx. 5 %) and the minimal distortion risk, the process is ideal for applications on wear-plates (wear-resistant composite sheets) or parts such as Fan Blades.


Besides Tungsten Carbide Coated Plates, HP Wear Resistant Group offers various products of wear plates namely Cr-Carbide Weld Clad Plates, Smooth Surface CCO plate, Heat Treated Wear Plates (AR Plate or Q&T Steel), Casting Plates in various grade and multiple size options.


HP Tungsten Carbide Coated Plates are made out of unique hard facing process combined with the specially formulated hard facing alloys produces the harder, tougher and better wear resistant plates.
