Anti Wear Tungsten Carbide Steel Plate 10mm PTAW Tungsten Carbide Steel Plate

Tungsten Carbide Steel Plate is made using the PTA process which has the great capability of producing well anti-abrasive surfaces. While the hard facing of PTA W Alloy Steel Plate 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 Resistant Steel Plates (Clad Abrasion Steel Plate) or parts such as Fan Blades.

Intrduction On Plasma Transferred Arc Weld (PTAW) Products

HP 750W products are developed for extremely abrasive applications and both the prime carbide and the matrix are very hard to be against abrasion.

This grade is made from spherical tungsten carbide dispersed in NiCrBSi matrix by Plasma Transferred Arc Weld (PTAW) process. The tungsten carbide is 70-75 wt % and the particle size is in the range of 60-325 mesh (44-250 micron) with hardness HV 2700- 2900. The bulk hardness of NiCrBSi matrix is HRC 60-70.

FAQ On HP Wear Products

Question: Can I cut or drill a hole in an HP overlay plate?

Answer: No. The chromium-carbide layer is not drillable or machineable. When necessary, you may be able to cut it with plasma, waterjet, or arc-gouging.

Answer: It depends on the hardfacing alloy. Many chromium carbide alloys check-crack when cooled to moderate temperatures; this is normal. Other alloys, such as the austenitic and martensitic, do not crack when applied properly. Check cracking can be seen as cracking perpendicular to the bead length. This occurs by the high stress that is experienced when the weld metal cools. The cracking stops at the parent metal underneath, as long as the parent metal is not brittle. If the parent metal is hard or brittle, you should choose a buffer layer of a softer, and tougher, weld metal.

Question: What are the most popular applications with hardfacing products?

Answer: The typical applications include  Mining Site, Steel Mill, Cement Industry, Power Generation, Glass Industry, Construction, Dredging, Oilsand, etc where need to fight with abrasion and impact.
