We, D-Tech, manufacture several types of D-Plate which are chromium carbide hardfacing wear plate in Vietnam and worldwide markets. D-Plate can be well used in various industries, such as cement industry, power station industry, steel industry and mining industry.
Wear plates and wear steel parts are used in many applications where friction between two parts or materials creates degradation.
Its wear-resistant chromium carbide alloys with 4.5 to 5% carbon added to sturdy carbon steel substrates. Wear plates are expendable items that are used to prevent excessive wear or damage to expensive equipment.
Abrasion resistant steel wear plate may bolt onto a machine that slides or rotates in a manufacturing process, while they can also be found where manufactured parts or minerals are regularly rubbing or abrasively contacting the surface.
Wear plate is commonly a type of abrasion resistant steel plate that is considered extremely durable, especially under harsh conditions.
However, various significant refinements and strategies have occurred. And as of present, the range of overlay wear plate accessible includes chromium and tungsten carbide grades, which possess excellent resistance to abrasion, impact, and erosion even at both ambient and elevated temperatures.
Meanwhile, in the more significant part of critical abrasion surroundings, the chromium carbide alloys are the primary profitable solution.
What types of material are wear resistant plate made of?
Alloy Chemistry
The highest ordinary used alloy facing is a high chromium iron consists of precisely 1/3 of Chromium and in surplus of 4% combined carbon.
D-Tech is making this to correlate to POP plate with the chemistry of Chromium of up to 34.0%, carbon of 5.4%, Manganese of 3.5%, and the others at 1.3%, Balance Fe.
Meanwhile, this standard alloy can be changed in many different ways; it can improve the abrasion resistance while lowering the toughness, or the other way round. On the contrary, the matrix can be made harder by reducing the manganese to 1%, with some reduction in firmness. Also, further refinement may be accomplished by the addition of other alloying elements.
Carbides
The substance that provides high chromium powder alloys with their capability to withstand abrasion is the establishment of primary carbides from a chemical compound of iron, Chromium, and carbon, or iron, Chromium, or carbide, which is also known as chromium carbide. Pure, high rate chromium carbide can be manufactured; however, it is costly for large-area preservation, so D-Techs makes use of mixed carbide, which involves both Chromium and iron. This makes up the primary carbide with the formula M7C3, where M specifies the mixture of metal and Chromium in the compound.
Hardness
A standard overlay alloy consists of a compound of chromium carbides in a matrix of a chromium iron-carbon alloy. The hardness of primary chromium carbides is proportionate of 1700HV correlate with. For instance, ordinary workshop steel files, with firmness of 600HV. In general, the hardness of these alloys can be calculated using a Rockwell hardness tester. Even though it neither measures the carbide or the matrix, it gives an agreeable general proof of the hardness of the alloy. An average value of being 54-60 HRC.
Microstructure
In the extension of chemistry, the most significant characteristic of the alloy overlay is its microstructure. Hence, when checked out under a microscope, the carbides will take the form of white substance against a dark background, that that’s the matrix. A perfect microstructure, for more excellent abrasion resistance, must have a dense array of needle-like carbides that, in cross-segment, look as slender hexagons with a small hole in the middle.
Moreover, whenever you notice an appearance of uneven shaped spots or avenues of white. Such as either ladder, fish-bone patterns, or central poles with rungs on any of the sides. This is a sure sign that the carbon content is beneath optimum for high abrasion resistance, but it has also improved impact-resistant properties.
How we supply for wear resistant plate?
- Wear Resistance materials: We manufacture solid welding wire and formulated powder by our own selves, with strict rule on the alloy composition.

- R&D Team: We provide an R&D team on both equipment and hardfacing technology.
- Customized Wear Products: We also supply customized Wear products in line with our customers’ demand.
What else should I know before I order my hardfacing wear plate?
You should know the what hardness of the plate is and what the intent is of the liner. The harder the plate that is used, the longer it will last in service, but there are trade-offs. For some parts, you will need a softer material that is intended to wear out before your primary surface.
