Basic Info

Model No.: Wear Plate_HP750W

Product Description

Plasma Transfer Arc Welding Products

Under the effect of high temperature plasma jet, the alloy powder and substrate surface are rapidly melted, and diffused together. The new substrate is generated as metallurgical combination of high hardness overlayer which can be well against abrasion and impact.

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.

Question: Is it normal to see cracking in hardfacing plating?

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.

Question: What metals can be protected with hardfacing?
Answer: Carbon and low-alloy steels with carbon contents of less than 1 percent can be hardfaced. High-carbon alloys may require a special buffer layer. Some of the base metals that can be hardfaced include: stainless steels, manganese steels, cast irons and steels, nickel-base alloys, copper-base alloys.

Question: What is hardfacing?
Answer: Hardfacing is also known as hardsurfacing. It is the process of adding wear-resistant weld metals to the surface of a metal part to protect it from wear and abrasion. Adding the weld metal plates can be achieved through welding or joining.
