In structural operations like mining, cement grinding, and steel smelting, wear is the leading cause of downtime. Machinery suffers from three primary types of wear: two-body abrasion, three-body abrasive grinding, and severe impact erosion. Standard carbon steel plates and even quenched alloy plates fail to provide long-term service lifespans under these brutal conditions. The development of high-density metallurgical powders and composite bimetallic cladding represents a major technical leap forward.
Traditional overlay methods often suffer from high dilution rates where the base steel plate's carbon is combined with the cladding, diluting the hardfacing benefits. Runxing's advanced surfacing systems utilizing precise metallurgical powders ensure stable chemical consistency. Whether depositing via open-arc, submerged-arc, or plasma-arc (PTA) systems, our processes limit dilution to under 10%. This allows the primary carbides to crystalize in their optimal geometric patterns, forming an impenetrable barrier against sliding wear.
Through close optimization of our alloy wire compositions, we guarantee uniform distribution of carbides from the fusion line up to the very top layer, ensuring consistent wear resistance throughout the plate's entire operational thickness.

The core of Runxing's wear-resistant technology is the Fe-Cr-C ternary alloy system. Upon cooling, the liquid alloy undergoes eutectic solidification, crystallizing primary M7C3 carbides. These carbides have a micro-hardness of 1200 - 1600 HV (Vickers), which is significantly harder than quartz particles (typically 900-1000 HV) and coal residues. The matrix surrounding these hard crystals is designed to be tough, absorbing high-stress impacts and preventing micro-cracking propagation.
| Alloy Grade | C (%) | Cr (%) | Other Elements | Hardness (HRC) |
|---|---|---|---|---|
| RX-7600 Standard | 3.5 - 5.0 | 22 - 30 | Mn, Si (balanced) | 58 - 62 |
| RX-Complex Carbide | 4.0 - 5.5 | 25 - 35 | Mo, W, V, Nb | 62 - 66 |
| PTA Ultra-Powder | 2.0 - 4.5 | 18 - 28 | Ni, B (matrix modifiers) | 60 - 65 |

A CCO wear plate is a composite bimetallic plate consisting of a standard structural steel backing (such as Q235 or Q355) and an ultra-hard alloy overlay deposited by arc welding. The overlay contains high volume fractions of primary chromium carbides, providing exceptional protection against sliding wear.
Flux-cored wire contains a hollow sheath filled with a core of mineral fluxes and metallic alloying powders. This allows high alloy content (such as Cr, C, Mn, B) to be easily introduced during welding, which is impossible with solid wire draws. Self-shielded versions generate their own shielding gas, allowing outdoor operation without external gas tanks.
Yes. CCO plates can be plasma cut from the back (mild steel side) or waterjet cut. They can be structural-welded to machinery using standard low-hydrogen electrodes on the carbon steel backing. They can also be cold-rolled to create curved chutes, pipes, and fan casings, provided the overlay faces inward or outward as designed.
VAUTID is a global leader in wear protection. As a certified VAUTID agent for six years, Runxing incorporates VAUTID's advanced metallurgy formulations. This guarantees low impurities, high primary carbide density, and reliable wear resistance under challenging high-temperature conditions.
