*2.3. CDP Plate*

Abrasion-resistant plates are manufactured by welding a sheet of non-alloy, low-alloy or high-alloy steel with shielded powder wire or self-shielded wire, as shown in Table 3 and Figure 3.


**Table 3.** Chemical composition of the surface deposit weld.

The deposited layer exhibits a very high abrasion resistance and has a standard thickness of 3–18 mm. Typical dimensions of abrasion plates are: 1000 × 2000 mm, 1500 × 3000 mm, and 2000 × 3000 mm. It is possible to cut flat elements of any shape from abrasion plates and further shape them by bending and rolling. They are joined to the regenerated substrate with fillet welds, continuous or intermittent, depending on the type of abrasive plate load. The high content of carbon, chromium, and niobium allows for the obtainment of a structure similar to that of cast iron with the inclusion of very hard chromium borides, niobium carbides, and iron carbides.
