Across the historical and industrial landscapes of Greece—ranging from the lignite mines of Ptolemaida and Megalopolis, the active bauxite extraction mines of the Parnassus-Giona zone, to the massive logistical hubs like the Port of Piraeus and Thessaloniki—machinery components suffer continuous, aggressive abrasive degradation. In these high-intensity settings, un-reinforced structural steel yields rapidly to the destructive power of quartz, alumina, and metal-to-mineral abrasion.
For decades, Greek industries have relied on conventional hardened steel plates. However, as operational demands intensify and global cost pressures rise, maintaining profitability requires switching to high-performance, bimetallic materials. By utilizing Chromium Carbide Overlay (CCO) wear plates, Greek heavy operations can shift from reactive maintenance to planned, long-term asset management, effectively multiplying service lives up to tenfold.

Learn MoreUnderstanding wear resistance begins with the microstructure of the material. Runxing's Chromium Carbide Overlay (CCO) plates are developed by welding a highly wear-resistant alloy formulation onto a structural steel base (mostly Q235B or Q355). This creates a metallurgical bond that combines the ductility of the structural plate with the extreme hardness of the overlay.
Our overlay contains a high concentration of primary chromium carbides ($Cr_7C_3$) embedded in a tough eutectic matrix. The microscopic hardness of these hexagonal primary carbides exceeds 1200 HV, whereas standard abrasive grains like quartz measure around 900-1000 HV. During abrasive wear, the hard carbides act as barriers, preventing the abrasive media from cutting through the matrix.
This bimetallic structure is compliant with DIN 8555 standards. It allows plates to be welded, formed, and bolted, making them much easier to fabricate and install than solid alloy castings or heat-treated manganese plates.
On a global level, manufacturing efficiency relies on reducing downtime. High material replacement costs, specialized labor shortages, and energy efficiency targets force operators to seek premium-grade materials. In Greece, these factors are particularly critical given the competitive pressure within the European Union market. By selecting Runxing CCO plates, Greek companies gain a strategic edge in the following ways:

Rolls, grinding rolls are roughly divided into two categories of rolls and grinding rolls, rolls are mostly used in the production line of iron and steel, continuous casting, open billet, conveyor and so on various materials of the rolls. Grinding rolls are mostly used in steel, cement, electric power, mining, etc., pre-material crushing, crushing equipment, coal mills, vertical mills, roller presses, crushing, and so on various materials of the grinding roll. The life of these rolls directly determines the service life of the equipment and affects the cost of the finished product, RX® has many years of experience in the repair of rolls and mill rolls. RX® has many years of experience and solutions to help companies improve the service life of their rolls and reduce their production costs.

Quenched & Tempered (Q&T) steels derive their wear resistance from martensitic heat treatment, but they are limited to a surface hardness of about 400 to 500 HBW, and their performance drops significantly at elevated temperatures. Runxing's Chromium Carbide Overlay (CCO) plates utilize a hypereutectic microstructure where chromium primary carbides ($Cr_7C_3$) are dispersed within a matrix. This overlay delivers a surface hardness of 58-62 HRC (600-750 HV) that does not degrade, maintaining abrasion resistance at high temperatures (up to 350°C for standard plates, and higher for custom alloy variations).
No. The cracks visible on the overlay surface are standard stress-relief cracks, which are normal for this type of material. During the hardfacing process, cooling of the high-alloy deposit causes residual stress build-up. The formation of these transverse cracks relieves this tension without reducing the bonding of the overlay to the backing plate, and they do not propagate into the mild steel base.
Due to the extreme hardness of the overlay, CCO plates cannot be cut with conventional mechanical saws or oxygen-fuel torches. Instead, they must be cut using plasma arc, laser, or waterjet cutting systems. They can be installed using plug welding, countersunk bolts, or by stud-welding structural threaded bolts to the mild steel backing plate. For curved installations, they can be formed in rolls with the overlay on the inside or outside radius, depending on the minimum diameter guidelines.
