Traditional carbon steel or even quench-and-tempered alloy steels (such as AR400 or AR500) lack the structural composition required to withstand high-stress grinding abrasion. This has accelerated the adoption of Bimetallic Chromium Carbide Overlay (CCO) Wear Plates.
A composite wear plate is fabricated by cladding a tough, weldable base plate (typically Q235B or Q355B structural steel) with a highly alloyed, wear-resistant coating. The core of this protection lies in the microstructure. During the open-arc or submerged-arc cladding process, the deposited alloy forms a hypereutectic structure containing primary chromium-rich $M_7C_3$ carbides (micro-hardness in the range of 1200-1600 HV) embedded in a ductile, austenitic matrix. The orientation of these primary carbides is perpendicular to the wear surface. This structural orientation prevents micro-scratching, grooving, and cutting action from moving abrasives, increasing equipment lifespan up to 10 to 20 times compared to structural carbon steel.
While standard steels rely on bulk hardness, CCO composite plates leverage a bimetallic system. The soft, ductile structural backing absorbs mechanical vibration and enables standard welding, drilling, and stud-mounting, while the hard cladding handles intense surface shear. This allows operators to run systems at peak capacity with minimized risk of brittle cracking.
A critical engineering parameter in CCO production is the dilution rate—the percentage of the base metal that melts and mixes into the weld overlay. High dilution dilutes the carbon and chromium content in the wear layer, reducing the volume fraction of primary $M_7C_3$ carbides and compromising performance. Tangshan Runxing Machinery Co., Ltd. controls dilution rates through advanced computerized welding control loops. Our four-gun system maintains consistent welding swing speeds and narrow-path trajectories to ensure a steep transition zone, preserving the targeted metallurgical properties of the wear layer right from the first millimeter of deposition.
As raw material processing facilities globally aim to optimize their operational expenditure (OPEX), material specification is shifting from commodity-grade structural steels to highly engineered wear-resistant composites. The global mining and cement industries face fluctuating ore grades and increased clinker throughput, accelerating equipment wear. Minimizing planned maintenance shutdowns has become a critical performance indicator (KPI).
In response to these trends, modern procurement managers are no longer sourcing simple plates; they seek integrated engineered components. This includes custom CNC-plasma cut chutes, pre-formed piping curves, and hardfaced rollers. Standardized testing, such as the ASTM G65 dry sand/rubber wheel abrasion test, is now standard practice for verifying the wear performance of incoming shipments. This guarantees that procurement departments receive overlay plates that deliver measurable wear life extensions.

To maintain our technical edge, we collaborate with Tangshan University. In 2023, the Dean of Tangshan University, the Vice Dean, and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology) visited our manufacturing base to conduct joint research on hardfacing weld overlay microstructures and dilution control mechanisms, ensuring our products remain aligned with material science developments.
Engineered wear protection designed to meet the operating conditions of key global industrial sectors.
The key issue for any cement plant lies in the availability of critical equipment. The key to equipment availability is wear resistance, and the performance of wear-resistant products determines the operating time of critical equipment. Applications include raw mill chutes, separator guides, cyclone bodies, and hopper liners.
